Posted a bug or a newbie question some time ago that I couldn't play mpeg2 (using the mpeg plugin). I have finally figured it out. I'm using AMD dual processors on a server motherboard. When the graphics card (NVIDIA GPU) is plugged into a PCI slot connected to the second CPU MPEG2 doesn't play... plug it into a PCI slot connected to the first CPU mpeg2 plays fine. All other formats play whichever port the card is plugged into.

An interesting bug for you guys to look at!

Uhh... I think the MPEG-2 plugin only uses the CPU, so I can't think of a reason why the video card would affect it, unless it was a display problem.

Same here.

You might try experimenting with different Decompression and Output formats in the "Video / Color Depth" menu. If Autoselect is chosen, the default for most MPEG video is "4:2:0 planar YCbCr (YV12)".

This just affects the raw data which the plugin returns to VirtualDub, but where it goes from there I don't know. Maybe he tries to hit the GPU directly at some level for some formats. That's about all I can think of...

May the FOURCC be with you...
