So the first thing to do is remove all the codecs you have on your system ,remove theatertek ,the nvidia purevideo ,even go into the registry if you have to and remove all traces .

Reboot ,reinstall theatertek ,reboot,start theatertek ,go into the video section and change the buffer to to less ,set video to full screen etc .

Hopefully this should sort out the problems your having ,i know it did for mine ,also i changed my nvidia drivers back to 81.85 ,as the new drivers were poor on my system.

Hope that helps.

Do you know what directory the Codecs are installed in? I will do extactly as you say. Thanks

Thanks Neilios

Tried removing all the codecs, installed Theatertek and it's now worse than ever. In fact, it is completely unwatchable! I am going to see if I can get the 81.85 drivers. Again, I might try a clean install. What is likely to be the bottle neck? My CPU useage is around 40% and my graphics card is a GF 6800GT. I know people have far better results with less spec machines and that is the most frustrating thing about it.

Are you sure the source material is clean and uncorrupted? Try a few mpeg2 demo files.

I have quite a few different HD videos inlcuding the original WMV DVD of Amazon. Doesn't matter if I play it on DVD or via Hard Drive. It all looks the same. I put on a normal DVD to see what it looked like and although it was much better, the jiddery movement was still noticeable. I'v tried downloading the older drivers but they don't seem to make any difference. All I can do is keep trying. Thanks for the suggestions guys. Much appreciated.

The new graphics cards from nvidia 7000 series and ati X1000 series have h.264 acceleration which will improve playback of HD content alot.

Try the Elecard mpeg player (free trial). When it comes to playback of HD, this baby is flawless.

It is the only player that plays 100% of my HD library and with supreme results. VLC and WMP+nVidia PureVideo only score 90-95% from me.

Thanks TheDoctor - I tried the Elecard Media player and you're right. So far, that is the best I have done. It still isn't smooth though but cerainly more watchable than ever. Thank you for that. Judging by the spec of your machine you aren't likely to suffer from lag problems Thanks!

I agree the new cards run HDTV better but the gripe I have is that people running older ATI 9800 cards etc are getting a much smoother picture than me. I think I'm going to upgrade to a AMD 64X2 chip and a new board early in the new year. Hopefully this will do the trick

I have been playing some hd demos on my laptop which is a P4 2.8Ghz, 512mb ram and a Radeon 9200 mobile graphics card. I've played numerous demos and most play with no stutter at all in the video but many really struggle with sound. So absolute power of the pc can't be that important imo as this laptop is only a moderate system.

The resolution of your laptop, and whether the source material is interlaced (and thus requires de-interlacing) can make a major difference in the performance of HD playback.

If you have a 1080/60i MPEG2 clip that you want to view, you can often get decent results on a lower resolution than 1920x1080 display, and if you de-interlace to 30p rather than 60p, or if the source is originally progressive 24p film, you can save a lot of processor overhead.

However if you want to watch a 1080/60i clip at 1080/60p on a laptop often you see the de-interlacing techniques eat into your processor power.

Other codecs like Divx and WMV are often only running at 24p - so have far less processing (as they are creating less than half the number of frames per second as a 60p de-interlacing process!)

Well I'm pretty new to the game so I wouldn't even know how to do half of that. Basically I've been using VLC without changing any settings and all of the trailers etc are 720p. I've hooked the laptop up to my plasma and it all looks awesome but the sound just isn't right.

Perhaps the demos have DD audio and VLC is not configured to use it or the laptop isn't setup to output DD via digital link to a suitable amp?
Even more basic have you got a direct show filter (AC3 Filter) installed?

I think that is correct. When I plated HD content on my PC the sound wasn't 'all there'. I soon found out that I didn't plug in my centre speaker. DOH!

All the HD clips I have played seem to be in 5.1 so this may well be the issue.

Very interesting stuff. Thanks

No idea if I have a direct show filter on this laptop. The laptop unfortunately doesn't have an spdif so I can't check that side of things.
