I think this file is exceptional and so it not working is probably unrelated to
whatever issue others are seeing.

It doesn't work because vdpau doesn't support field coded mpeg2. I guess
because it is very rare - other than compliance streams this is the first one
I've seen in the wild, and given it's mpeg2 in mkv with ac3 and the cartoon
content is a mix of progressive and interlaced (maybe from telecine and frame
rate converted) I don't know if it's an amateur creation or something "real".
