When I run it on my Athlon MP (2.13GHz) I get that output after 900 frames: ps ax -m -L 11405 - pts/4 - 0:13 lav2yuv john.eli - 11405 - S+ 0:13 - 11406 - pts/4 - 0:01 buffer -b 2048 - 11406 - S+ 0:01 - 11407 - pts/4 - 12:00 lt-y4mdenoise -p 2 - 11407 - Rl+ 12:00 - - 11424 - Sl+ 0:01 - - 11425 - Sl+ 0:01 - - 11426 - Sl+ 2:41 - 11408 - pts/4 - 0:25 mpeg2enc -f 8 -4 1 -2 1 -q 5 -P -N 1.0 -M 2 -E -10 -D 10 -a 2 -o test_p1.m2v - 11408 - Sl+ 0:25 - - 11423 - Sl+ 0:03 - - 11427 - Sl+ 0:31 - - 11428 - Sl+ 0:29 - Is this something you expected ? auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
