I have a script to convert to h.264 using mencoder.
See http://www.mythtv.org/wiki/Mythnuv2mkv

I won't put the full details here. It's options are
mythnuv2mkv.sh [--jobid=%JOBID%] [--contype=avi|mkv|mp4] [--quality=low|
med|high|480|576|720|1080] [--pass=one|two] [--denoise=ON|OFF]
[--deblock=ON|OFF] [--deleterec=ON|OFF] [--crop=ON|OFF]
[--deinterlace=ON|OFF|SOURCENAME] [--invtelecine=ON|OFF]
[--outputchecks=notype] [[--chapterduration=mins] |
[--chapterfile=file]] [--maxrunhours=int] [--findtitle=string]
[--copydir=directory] --chanid=chanid --starttime=starttime | file ...
See the web page for descriptions of these.
Also there are quite a few dependencies, again see web page.

As a user job run like
PATH/mythnuv2mkv.sh --jobid=%JOBID% --copydir=/mythvideodirectory
--chanid=%CHANID% --starttime=%STARTTIME%
This will convert nuv/mpeg recording to h.264/aac/mkv and copy it
to /mythvideodirectory. If /mythvideodirectory is a MythVideo directory
imdb will be searched and a MythVideo entry created.
--contype=mp4 will create h.264/aac/mp4 video.

(Note/ Probably won't work with Myth 0.22)
