First, I suggest to enhance the probe code to increase a bit the score
when extention matches a known file format. This is what the DV demuxer
was using before the probe function unfortunately.
Then I suggest we revert the support of spacejam*.dv until we find an
adequate solution. "pond.dv" has IMHO preference since it was working
Furthermore, I believe if we add a new demuxer for this case, we should
add a new demuxer for every format having a startcode and can be "in the
middle of a cd image". I find this definitely non reasonable.
