Except that's not how MPEG compression works. Your bitrate determines your file size not the amount of noise in the image. Sounds like the OP is using software encoding and their machine is having problems keeping up with the encoding and is dumping MPEG4 in favor of mjpeg which is less CPU intensive. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
