a friend of mine gets this error when trying to run sof2 mutliplayer:

Unsupported marker type 0x1d


------------- Input Shutdown -------------

the unsupported maker type changes from 0x1d to things like 0x2f, and all sorts of stranges #s..what can he do? I tried it on my computer and it works fine
he runs a duron 950, 512mb ram, geforce 2mx 400 64ddr ram and currently running xp
should he run the det 30's or 40s?

any input would be greatly appreciated
