Things tend to break when the DVD layer has to go through the cache as
some information gets lost (e.g. you can't ask the DVD for the position,
because that's the position that is being cached, not the one played).
I haven't tracked down the exact cause, but in case you haven't noticed
-demuxer lavf plays it.
