Good to know if I use more of the mjpeg_tools (i.e. mpeg2enc, mplex, yuv*, etc.) in the future. > Than the mpeg encoder does not spend much bandwith for that ares. I am not using the mpeg2enc encoder. It is way too slow for my causual (encode, watch once and then delete) encoding needs. > Lookes correct.

Problem is that when encoding to a given bitrate, the improvement will be a subjective visual quality (hard to quantify), not a file size difference. Maybe I could see if mencoder has a constant quality setting and see if there is much of a file size difference there. Thanks much for your input though. b. -- Brian J. Murrell
