The version I was given by the author does P and B frames too but
doesn't do motion compensation (yet?). Its not a public release tho -
you should contact the author for source...

The stand-alone players I'm aware of all expect VCD format (which has
some sync information in the sector info as well as the actual MPEG
payload). The directory structure is essentially ISO, but the
actually video track(s) are in a special CD-XA MODE-2 format.
However, PC based hardware players basically seem to play most
"reasonably VCD or DVD-like" MPEG-1 and MPEG-2 streams. However my
DXR2 does expect to be told its playing a "pure" MPEG-1/2 stream
rather than a VCD stream or a DVD VOB.

Odd ... I couldn't persuade you to try MPEG-1-ing the MJPEG's with the
mjpeg version of the MPEG tools? It'd be very handy to find out if
there's a glitch in the MPEG syntax generated that the Linux players
ignore.
