Actually, even on streams that I have re-encoded through mencoder or other means and I *know* the bitrate is 4000 kbps, I get that exact bit rate output from tcprobe -i (104857, which, in hex, is conveniently 19999). I would say that tcprobe -i is not reading the info correctly, or that the encoding software is not setting the correct bits in the MPEG header somewhere. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
