Well, but this will be generally caught by a checksum.  Just repeating
the packet headers are in general not going to be an effective (nor
efficient measure).

I'm just curious what kind of data would be retained.

One image in a movie, e.g. 1/25th of a seconds worth, or similar.
Having a separate packet per frame sounds like a lot of overhead.

Guilty, I suppose. I can't keep up with all the posts on
mplayer-users, so I only read it sporadically.  And I haven't use file
sharing, so I've naturally not encountered this problem.  Okay, so I
should probably have stayed out of the discussion. :-)

If I haven't seen further, it is by standing in the footprints of giants
