I did consult mplayer documentation, Paul. And Google's useless for stuff like this: A half million 
hits showing "How to play videos". When the person doing the search (me) is so unsure, forming a 
meaningful search string is difficult. You folks are the pros. I hope you can provide the guidance.

Look, this is really a side trip. I just wanted to see whether 55-telecine would work with a DVD 
video that's as long running as the BD videos -- the ones that ffmpeg can't 55-telecine without PTS 
errors. PTS errors is what really needs to be fixed. For now, this is just a distraction.

Carl Eugen reminded me of 'mplayer -dumpstream'. As you know, I've been rather busy lately. Well, I 
can't get 'mplayer -dumpstream' to work with a string of VOBs. ...But it's just a distraction.
