[MEncoder-users] Any recent changes that could affect MPEG 2 muxing?

[L. Lee]

If I execute a mux command to adjust A/V sync in an MPEG 2 stream such as
mencoder [inputfile.mpg] -ovc copy -oac copy -ofps 24000/1001 -of mpeg
-mpegopts format=dvd:tsaf:adelay=-200:muxrate=40000 -o [outputfile.mpg]
using MEncoder svn r32924 (as well as quite a few previous versions),
everything works well.

If, however, I execute that command using r33094, the audio tempo appears to
be increased greatly, demolishing sync, and the command progress output
includes many duplicate frame notifications. The visual output remains
unaffected.

Has something changed that can be accommodated by adjusting any of the above
command options? The source video is 24 fps with 6-channel audio (AC3).
Thanks.
