Should I use Direct TV for Off Air Locals

This is not an antenna question:

I just bought a new HDTV that has a HD tuner. Should I run the off air directly to the HDTV tuner or continue to use DirectTV to decode the signal? I've heard that DirectTV's compresses the HD signal to save bandwidth, so I was wondering which would provide the best picture?

So are you running your off air cable into the HD receiver's off air in? If so .. you must have an older receiver. What you need to do is run the coax from your off air directly into the coax connection of the tv. This is due to the fact that your off air comes in on around 250mhz. This is the same frequency that the HD uses. DTV has found that this can cause interference This is why the new HD receivers don't have coax inputs for off air signal.

Hope this helps.

I have the newer receiver (piano black) but I also have the AM21. So, are you saying I will get a better picture if I connect the off air directly to the HDTV, rather than letting DirectTV decode the signal?

I am also interested in the anwser to this question. As I understand it, the CABLE companies, have to compress the signal due to bandwidth limitations, so I was told the over the air HD signals provide a better picture. I was not told this also applies sat. tv signals.......I am sure someone here knows.......

Correct. OTA delivers the best HD picture as it has less compression.

If you have the AM21 and getting your locals OTA then they aren't compressed. DirecTV doesn't do anything to the signal. If you go through the AM21 then your OTA channels are incorporated into your DTV guide and you're able to record the channels. If you have the OTA connected to your TV then you can watch but not record.

With that being the case, I will continue integrating my OTA signal with DirectTV, via the AM21. This provides the same picture quality with the ability of recording with the DVR.

Thanks
