OK. Have you setup your transcoder profiles properly?

If you run this query in mysql what does it show?
SELECT r.* FROM recordingprofiles r, profilegroups p WHERE
p.name='Transcoders' AND p.id=r.profilegroup;

If the videocodec and audiocodec columns are all  NULL then you need to
setup your profiles properly. TV Settings->Recording Profiles->Transcoders.

Try running mythtranscode using one of the id's you see in the table for
the '-p' parameter rather than using 'autodetect'.
