[MPlayer-users] Can somebody explain this? (and some trouble with mpeg muxer as well - i guess)

[Vijay Gill]

Hi,
   I use mencoder to encode my mythtv recording into DVD compliant MPEG2
format.

   If I use profiles (mencoder config fille provided at the end), then speed
is half of what I get by not using profiles and passing all those parameters
in command line. Examples of command lines are provided at the end of the
mail.

   The problem with the muxer (which I assume is a problem because and old
version of mencoder (CVS of 2006-01-13 ) does the job without any problem)
is that it starts throwing following messages almost 10-20 seconds down the
line during encoding and the resulting file does not play(freezes) or has
sound problem.

I have not tried to find which day's CVS version actually started causing
this but definitely after the date mentioned above.
