Then that would have both the new default of -R 0 as well as the --no-dualprime-mpeg2 (I think you found it :) ) switch. > > some B frames (and turning off DPME), or to use the "no DPME" switch > > if you are running the absolute latest CVS (search the archives for > > the name, it was posted in the last month or so). > > --no-dualprime-mpeg2 > I suppose?

Both achieve turning off DPME, but in two different ways. The mpeg encoding spec that mpeg2enc follows excludes use of DPME if B frames are being encoded. So encoding B frames implicitly also turns off DPME. The special switch provides a way to disable DPME, while still allowing you to encode without B frames. Either switch should (if DPME is the problem) fix things. Setting -R to 1 or 2 will likely encode more slowly than -R 0 and --no-dualprime-mpeg2. And there may be differences in the resultant file sizes as well. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
