Interesting read. Some remarks:

- The MPlayer problems are unlikely to be related to qt4l/cinelerra.
  MPlayers mov-demuxer is a complete disaster, I saw it crashing many times
  with perfectly correct Quicktime files. If you want, you can try ffmpeg/ffplay
  instead. It has an own mov demuxer and many people use ffmpeg for transcoding
  cinelerras output.

- Strange that cinelerras Motion-JPEG-A output is not supported by 
Quicktime-7.x.
  I did some tests with libquicktime and Quicktime-7 (Win XP) a while ago and 
found,
  that MJPEG-A and JPEG-Photo work fine with QT7 (audio was Twos complement,
  16-bit linear).

- You mention that no dithering was used for audio. That's ok, but shouldn't 
affect
  compatibility of the final file (Dithering is done before encoding to convert 
the
  64 bit internal representation to 16 bits).

- I regularly use JPEG-Photo and 16 bit Twos complement and found, that 
cinelerra
  reads all .mov files generated by libquicktime, and cinelerras .mov output 
can be
  decoded by all decent decoders.
