There is one more thing, with:

mencoder -noskip -of mpeg -mpegopts format=mpeg1 -ovc lavc -lavcopts 
vcodec=mpeg1video -o PC290052.mpg PC290052.MOV

I get many errors:

ERROR! unknown fps code: 0INITIAL DELAY of 0 framesmb  A-V:0.000 
[867:0]]   0mb  A-V:0.000 [0:0]

    etc

However, since mplayer had no problem with the result, I assumed it did 
not matter.

Perhaps these problems are why the other players are having problems.
