HD playing problem

[sleighty]

Hi All
I hope someone can help me or point me in the right direction, I'm have problems playing HDTV and HD movies on my media center, every thing else works fine. The picture and sound stops and starts like its bad reception and I did think it was the TV card at first but it happens with download HD film as well. I have the correct res for the TV so theres no problem there. Any ideas for a first time noob :)

AMD Sempron 2600+,Gigabyte GA-7S748, 2 GB Memory,Radeon 9600,compro t-300, Windows XP (SP2) running it to a LG 50" plasma

I hope I posted this in the right place?

Upgrade your video card.

SO your saying that the Video card is not up the job? Would a ATI Radeon X800XL 256MB 256-bit DDR3 card do a better Job as I have one of these in my main computer.

Guess I could give it a go.

Yes, that would be a much better card. HD video requires a fairly robust video card for smooth playing video, especially if you're using Windows Media Center.

Did you check your CPU usage? I bet you're pegging at 100%.

I'm using media portal but it happens with any player I use, the cpu gets high but dosnt hit 100%, only on and off.

I playback 1080i HD TS material just fine on an Athlon 2400+ 512mb RAM with a Radeon 9500 Pro. I use the CPU intensive Unofficial Dscaler decoder with 1080i IVTC in Zoomplayer.

I don't use hardware acceleration either.

Try your better video card for sure, but I think your hardware may be up to it (just).

The better card didnt make much of a difference? any other ideas?

Combined with Reclock (you need a 48hz/72hz capable display like a CRT) I get very smooth playback of 1080i film based material.
