[mythtv-users] Transcoding Proglems With ffmpeg

I'm an Ubuntu user and can't transcode. I read that this is due to a
problem with the default version of ffmpeg, so I compiled the latest
SVN code from source. Here's the configure command that I used:
./configure --enable-mp3lame --enable-libogg --enable-vorbis \
> --enable-faad --enable-faac --enable-libgsm --enable-xvid \
> --enable-gpl
This successfully installed ffmpeg under /usr/local/bin. I then
deleted the Ubuntu version so that MythTv would be sure to pick the
right version.
THe problem is that I'm getting the following error message in my
mythbackend log file when I try and transcode:
2006-09-26 21:22:57.513 Transcoding from
/var/lib/mythtv//1003_20060924200000_20060924203000.nuv to /var/lib/mythtv//1003_20060924200000_20060924203000.nuv.tmp

This is the same error that I got before I "fixed" ffmpeg. I then
tried to convert the same file using mythtranscode. Here's what I
got:
/var/lib/mythtv$ sudo mythtranscode -i 1003_20060924200000_20060924203000.nuv

Segmentation fault
Finally, I'm using the 0.18.1.20050510-1 version of MythTv, the
default version available to Ubuntu 6.06 users.
Does anyone know how I can begin to troubleshoot this problem? I
don't know what to try next. Any help would be greatly appreciated.
Thanks again!
