I do not have any problems using mythtranscode to go from MPEG2 to MPEG4.
Actually I do transcode all recordings immediately to MPEG4.
However if I use mythtranscode in 0.18.1 to cut out commercials of an
already transcoded recording, I get severe problems (database corruption,
problems when skipping forward). I did not have these problems in 0.14 or
0.16, so I hope they are gone again in next release.

I have had audio-sync problems with most of the export options in nuvexport.
Apparently some of the programs used do not handle the timestamping inside
the nuv-files. However I have not seen audio-sync problems with the DIVX
exports.
