Hi-res two-screen playback

[Andy Millns]

Hello,

I am looking for advice on hi-res video playback using BSPlayer across two screens (for stereoscopic video playback). Does anyone have any advice on codec and hardware choice for playing back at the following spec:

25fps
2048 x 576 resolution video (widescreen aspect, 1024 x 576 on each monitor)
Surround Sound - AC3 or equiv.

I have had some luck with 3vix at lower resolutions but it seems to be a bit hit and miss, with frames being dropped. With 3vix and DivX does the bottleneck for hi-res generally occur at the processor or the graphics card? What can I do to improve performance?

Sorry if these questions are a bit out of the remit of this group.

Thanks.

Not possible with ATI radeon's as far I know. I think its A windows error that doesn't allow spanning of AVI's MPG's ... over multiple screens

I've tried it on various GeForce4's and it will certainly playback in both windows fullscreen. Windows media player and various other players I've tried do not work over two screens.

The problem I'm having is with performance, it's almost there but I wanted to know if anyone has any tips in order to get the optimum performance. Incidentally, I've tried the new Windows Media HD encoder and when it works, it works well but the software is just far too flaky, especially the Premiere plugin.

The only advice I can give is to use ffdshow. It is less consuming than other decoders. I usually recomend it for slower CPUs.
