Nvidia G-Force 7900GS
Athlon X2 Dual Core 4200+2.21ghz
Ram 1 gig
Win Vista Ultimate
Apex mother board

Trying to play HD via dvi to hdmi cable to my 47' tv, looks crappy, cropped, and skips. I experimented with 720p and it plays but doesn't look that great. Tried many different codecs and codec packs yes I googled it. I am thinking its time for a new PC.

It should play all 720p and most 1080p (at lower bitrates) fine. YOu probably don't have your filters set up right.
Try to disable all codec packs and get:

ffdshow or (buy) CoreAVC
Get AC3filter version 1.46

That's about all you need. CoreAVC will use fewer system resources. Just be sure to utilise these tools to decode your videos. This might be troublesome if some remnants of your codec packs remain.

Thank you this worked, I "bought" CoreAVC and 1080p playback is smooth now I'm just trying to configure the video to fit my TV screeen, trying zoom player & MPC and tinkering with different options, any special method for this? For some reason the Nvidia software will only let me use the use same dispay on both/clone (the monitor and tv) (btw the monitor is FS and TV is WS) option so I think this is my problem. Is there any third party app that will assist me? AFAIK I have the latest Nvidia drivers I will double check.

I think I will install XP on another partition and dual-boot to it for only HD video playback to eliminate some variables.

Thanks again for taking the time to reply.

Dual view is the best way to run 2 monitors. Vista may not allow that mode, so you will be better off to use XP for a HTPC. With dual view and your Nvidia card in XP you should be able to open a media player like Zoom player or MPC in a small window on the computer monitor and it will play full screen on the second HDTV monitor, I think Nvidia calls this "full screen video mirroring" when running in the Dual view mode. If you want to run this mode do not get the Nvidia 8500 or 8600 cards as they will not work with full screen video mirroring. Also Power DVD will have to be started on the monitor you want it to play on as it will not play on 2 monitors at the same time, another DRM limit, but Zoom player and MPC will play on 2 monitor just fine.

If your HDTV monitor is native 1080P then you should run the 7900 card at 1920X1080 and have no resizing in the 7900 or the HDTV to get 1:1 pixel mapping when playing 1080i or P movies, this will usually result in some overscan on the HDTV monitor as most are designed to have overscan.

Ok I have it in dual view but all I see is my desktop wall paper but it is over to the right of my normal desk top as if an extention of the desk is to to the right. If I play a movie in fullscreen or windowed I see nothing. If I drag the the window all the way to the left side of the screen it will show on the tv any portion or all that is off the screen. Wierd. I tried to run the computer monitor in 1900x1080 but it cannot do it. I'm thinking if I make the HDTV my primary monitor this may work. My HDTV is 1080p native by the way. Thank you for taking the time to answer I'm not completely there but I'm closer, more trial and error and help from my friend google should do the trick.
