[MPlayer-advusers] [BUG] "too many buffered pts" with VOB + -correct-pts

[Alexander Strange]

http://astrange.ithinksw.net/so.vob (first 10mb of a DVD title)

Playback shows garbage on screen instead of most of the video,  
presumably from dropped packets.

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

Too many buffered pts
Too many buffered pts
(repeat forever, sometimes with "pts value <= previous", which by the  
way is missing a trailing \n)

All three of these work:
* -no-correct-pts
* -demuxer lavf
* mkvmerge -o so.mkv and playing that

I didn't check to see if the A/V sync and all were correct, but they  
play.
All three have the wrong aspect ratio (should be 720x528) but whatever.
