Well, maybe your souncard uses 16bit DMA channel that allows for crisp
sound, while mine only has 8bit DMA. Or you're using a smaller
resolution/refresh rate than me. Or your motherboard is able to allocate
necessary bus bandwidth to both SB16 and Virge, while mine isn't. I don't
know.

Weird. When I did have NT 4.0 on my machine (not anymore) I was able to
play everything. Microsoft did not yet "innovate" asf/wmv crap back then,
but mpeg-1 were played fine.

I know. Time to buy better hardware, it seems.
