One thing I found out: the MPG from Sony consists of a series of
complete frames, while most other MPGs consist of incremental frames. 

For example:

    mencoder -of mpeg -ovc lavc -lavcopts vcodec=mpeg1video \
        -oac copy mov00000.mpg new.mpg

This will produce a new mpg of about 2.8Mb out of an 8.6Mb original.
