[MPlayer-users] Some DVDs have no video with cache enabled

[Josh]

This is a really old bug (there are a lot of recent commits so to 
clarify they weren't the problem). Some DVDs (usually ripped) don't 
display video when caching. I usually stream them over the network which 
is really slow (with my particular internet service there is no choice 
but to use their router which is only capable of 130Mbps wirelessly) so 
it is necessary to use the cache. It can't be the ripping software 
because doesn't happen to all of them (the vast majority work fine with 
caching but often one won't work when using cache). There are no 
problems playing the VOB files directly as files with caching.

I uploaded a truncated DVD to /incoming as 'dvd_novideo_with_cache'
