Default more info?

Well what is you setup, like what graphics card do you have, cpu and memory, is your monitor type? Are you going through an HDTV? There is an app called belarc that can tell you what you have on your system if you can't find out you specs.

Well the only problem is my cpu and memory. Its not that great. I know I would probably need another video card.

Pentium 4 1.8ghz
768mb ram
120gb hard drive.

I know its weak............

Yes I use my HDTV as a computer monitor. Its just a 26incher, again nothing fancy.

Actually that CPU is kinda weak for anything with a decent bitrate. You either need more computer or a video card that does acceleration. You can pick up a Nvidia GT6600 for very little now and with "purevideo", Nvidia's accelerated HD drivers, you should be able to play most stuff.

An example. My machine is pretty strong, an Opteron 165 at 2.4 Ghz, but I have a 1080i 18Mb/s vid that uses pretty much all of one core if I do not use hardware acceleration. About 30% with.

You would have no chance of playing that unaccelerated.

Not to be off subject, but are you OC'ing your opteron? Me thought the165's were a 1.8 dc? If you be OC'ing, what method, and how stable?

One solution would be to get a MDP-130 ATSC tuner card for your computer. It has onboard video and decoders that don't require a powerful computer to output HD because the computer CPU does not get involved with any of the decoding or video output. For more info see: MyHTPC

I have one of my HTPCs that has this card in it that is only a 866 P3 and it works perfectly.

The issue you will have with a card like the MDP-130 is when you download a video from the internet, if it is not a transport stream the file will need to be converted. I have several conversion programs that I use to make transport stream files out of other file formats. Once converted, the files play without any problems. The card will also play and upconvert regular DVDs also.

So your choice becomes getting a killer computer with a killer video card and a lot of RAM or going for a card that does all of the work. I chose to go with the MDP-130 at under $150 and buy a bunch of hard drives for storage.

in regards to media players.

I like the VLC media player. plays just about everything and it is free.

even plays vs files ,1081i, 720p, dolby, dts, dvds in PAL and ntsc, etc.

I had to do some upgrades before I could play HD DVDs smoothly. I ended up getting an Athlon 64 4400+ dual core with an ATI Radeon X1650 pro with built-in HDMI & HDCP support. I couldn't find a single piece of hardware that would take 100% of the HD decoding load off of the CPU.

I just tweak the BIOS on my AN8-SLI board. It's actually fairly comlicated. The Opterons clock well, not quite as well as my Venice 1.8 Ghz but well. It'll do 2.8 GHz but 2.4 seems to be the sweet spot. Plays games in windose even, a harsh environment .

First of all, what do you mean when you say "hardware acceleration"?
And second, is my Nvidia GeForce 6600 the same thing as ur GT?

You are connecting vis VGA? I dont think you can get 1080 signals can you? I thought you needed DVI/HDMI...

Anyway, try getting a GPU with "purevideo". Itll offload the decoding to your graphic card, leaving your cpu free to do other things.
