This works for me as far as the "marker does not match f_code" messages 
are concerned, thanks.

But I see a very strange effect when playing DivX videos through 
ffodivxvdpau now: it looks as if every second frame were dropped and the 
first one instead duplicated (or even worse), all movements look choppy. 
This is not related to this patch. It doesn't happen with the software 
decoder and doesn't happen with the VDPAU decoder and r36171 from Fedora 
repositories.

I seems that ffh264vdpau is not affected.

Thanks,
