Help!! Video and audio glitches

08-10-2005, 03:43 PM
I have the Hughes Direct TV with Tivo H10-250. I am using component video connection because I had a problem with the DVI connection as many people did with this unit. I get video and audio glitching almost exclusively on the High definition channels. I get this on satellite AND on antenna High definition. I really do not believe it is a signal strength problem because the signal strength on the 119 satellite is around 90. The 110 satellite is around 70-75, but I think most of the High def comes through 119 satellite. Also, the signal strength on the antenna channels looks just fine. Basically I get freezing from time to time. Sometimes it can be as much as 4-5 times during an hour show. It is very distracting. Sometimes I get none at all for 4-5 shows in a row. It is not limited to any one HD channel although I get a lot of glitching on UHD. Since I get glitching on satellite and OTA, I suspect it may not be a problem with the cable connections either.

That seems to leave the Hughes unit itself or the fact that High def broadcasting is inherently glitchy at this stage. I really hate to hastle sending back the unit if it isn't the unit causing this problem. I have had direct tv out a few times to adjust signal strength. I live in the Los Angeles area.

Any ideas????

Lets try to narrow this down a bit,
You say you are getting pixialation on D* as well as HD channels,,
Are you using an antenna for the HD locals (I presume your talking about local HD, although maybe not).
Is this an indoor or outdoor antenna ?
Are you running this OTA antenna thru your HD receiver or right into the TV ?
If you have a HD tuner in your TV , try running OTA antenna directly into TV and see if you still have the trouble, if not, I am leaning towards the faulty receiver, although bad coax connectors can also cause trouble.
Is there a multi switch involved also ?

Thanks for the quick response. I am using an external antenna that is running through the HD receiver. I am talking about local HD channels with regard to the antenna. I do not have a separate HD tuner in the TV. There is a multi switch involved. I have two other TVs hooked up to the triple dish and they do not glitch but they are not HD.

I just discovered that many of the HD channels now appear to be on the 110 satellite. Did Direct TV switch the HD channels around. Now, it appears that UHD, ESPN HD, HBO HD, HD net and Showtime HD are all on the 110 antenna. In the past they were on the 119. If this is true, maybe I do hava a signal strength issue since my 110 satellite strength is around 70 or so.

Anybody know about Direct switching the HD channels from the 119 to the 110 satellite????

They are on the 110 sat. Check it out here:http://www.lyngsat.com/packages/directvusa110.html

Thanks for the reply. That's the site I found indicating these HD channels are on the 110 satellite. I called Direct TV and the tech guy insists that for my area (Sherman Oaks, Ca) that all the high def channels are on the 119???????

I've found Lyngsat to be acurate and up to date. Why not run set up again for your receiver and pick oval dish, 2 lnbs and see if you don't get any of the HD channels that are on the 110 sat. Then you will know for sure what is on the 110. With that set up, you only receive what is on the 101 and 119 sats.

Thanks Spiderman. I will try that. I have Direct TV coming out again this weekend to see if they can figure it out. You can't get a straight answer from anyone at Direct Tv as to which channels are on which satellite.

I'm starting to suspect the receiver as the possible culprit, since I get glitching on both satellite and antenna high def channels. I can't see what else the two (satellite and antenna) share in common to cause this problem. They both run through the receiver, but they have separate cables to the receiver. If it was a cable or multiswitch problem, I don't think both antenna and satellite would be impacted.

I asked Direct Tv if they could bring out a high def receiver to plug in to test if that was the problem, but they don't do that. That, of course, would be the easiest way to determine if the box is bad. If another high def receiver has the same issues, it would not be the box, but if the replacement worked ok, then the box is the culprit. Anyway, thanks again for the suggestion.

My HD Tivo box has been doing the same thing since I got it. I also have a second one in another room. Both do it as bad. DirecTV said is was signal strength. We tweaked it and got a bit more. Everything is 80 or above and we still get the same thing on HD channels only. Annoying as hell. Some nights, no problem, other nights it can be so bad you just switch over to the non-HD version. American Idol was so bad last season we just watched the non-HD broadcast.

I completely lost picture once, had to do a full reset. Other than that, it's been the freeze frame or audio stop.

Direct TV always says its a signal strength problem, but I have a strong feeling that something else is going on here. Since you have two boxes with the problem, it's hard to imagine its the box causing the problem. Maybe HD is just inherently glitchy at this point. Seems like more people would be complaining about this though, if that was the problem. Maybe HD is glitchy in certain areas that have some type of interference (Planes perhaps). I have planes fllying overhead pretty regularly, and I wonder if that could be the problem. Are you in an area with plane traffic, perhaps?? It is really annoying. Do you have OTA High def as well, and if so, do you have a problem with the antenna high def? My high def glitches on antenna as well.

Could there be a problem with the High def Tivo boxes in general. Mine is a Hughes 10-250. I think that may be the only high def Tivo box out.

Direct TV is coming back out this weekend and I'll let you know if anything gets resolved, but I am not optimistic.

I'm a bit late getting in on this thread but I too have the Hughes HD/Tivo unit and mine is horrobly glitchy on HD channels only. Sometimes it is so bad I can't even watch it and seems to be more frequent. My signal strength is 88 or better on all satellites. If anyone has seen a fix for this please post. Direct Tv is no help at all.

Just a thought. My Hughes H10-250 is hooked up through Component video rather than DVI, since the later didn't work properly. Any one had any problem with video glitching through component video cable? Is it possible I need to upgrade the comonent video cable? I bought relatively inexpensive component cable originally since I didn't have high def at the time, just a dvd player I was hooking up. The dvd player works just fine, but maybe high def places more of a strain on the cable. Could that be causing the video glitching on high def channels. It seems to be the only common connection on my system since both Satellite and OTA high def have video glitching. Would a higher grade component video cable possibly solve the video glithcing issue???

The HR10-250 does not have DVI it has HDMI. Have you tried using it?

08-17-2005, 11:38 AM
Sorry. I meant HDMI. The HDMI doesn't work properly on the unit. I understand that many people had trouble with HDMI failure on this unit. I read somewhere that 20% or so of them were defective. That's why I used the component video cables instead. The picture is great on the component video because my tv is a CRT. But, my concern is whether the component cables could be causing the video freezing problem I am getting. The HD picture is great except for this glitching.

The problem that you read so much about was for the H-10 which is not a DVR. Try using the HDMI. If you wish to stay with the component make sure they are seeded securley. I had one of mine come loose some how and it drove me nuts. Then I just made sure they were in securely and my probem went away. But try the HDMI first.

08-17-2005, 12:27 PM
Thanks. I will try the HDMI again. When I tried it I got no picture. The TV setting was correct. Do you have to reboot the Tivo box or change a setting on the Tivo for the Tivo to recognize the HDMI, or just plug it into the proper place???

08-17-2005, 01:14 PM
You should never plug or unplug any cables with power on. With HDMI/DVI the TV should be powered & the HDMI input selected BEFORE you power up your STB.

08-17-2005, 03:29 PM
The problem with the HDMI interface has been reported not only for the H10, but also for the Hughes Tivo H10-250. There has been a large percentage of HDMI failure with the high def Tivo boxes. See Tivo Community for threads on this problem with Hughes Hi def box

08-17-2005, 04:33 PM
Until now I had not been aware that there was a problem. From what little I read at the Tivo Community site , it sounds like a whole different problem than the H-10 had. If this problem is as bad as you say there are going to be a whole lot of pissed off folks that are jumping all over the new offer from D. ($299 with $100 rebate)
If you decide to try the HDMI connection I don't see anything in the manual about doing anythig special when hooking it up. (unlike the HTL-HD) Just as RSawdey said, unplug it first. If you decide to stick with component connections. Before you go spending money on new cables, just make sure that you have a good connection with the ones you are using. Same should hold true if you go with the HDMI. I have read and seen for myself that they don't always fit snuggly.
