Most likely your problem is that you haven't set, or have improperly
set transcoding parameters in your FE, Utilities/Setup -> Setup -> TV
Settings -> Recording Profiles
-> Transcoders.

You can find your current transcode settings by running the SQL command:
mysql> select r.* from recordingprofiles r,profilegroups p where
p.name='Transcoders' and p.id=r.profilegroup;
