I wasn't aware that mythtv cut out commercials and recorded them as separate files. If so: 1) why not simply *delete* them? 2) wouldn't it have to also record the *exact* same file contents? I suppose there may be an mpeg-diff that could determine that 99% of two files are the same video content. If not, could be a good project for someone. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
