Edit mythtv/programs/mythtranscode/transcode.cpp and search for
Transcode::GetProfile.  In that method, you'll see the following code:

        if (encodingType == "MPEG-2")
            result = profile.loadByGroup("MPEG2", "Transcoders");
        if (encodingType == "MPEG-4" || encodingType == "RTjpeg")
            result = profile.loadByGroup("RTjpeg/MPEG4",
                                         "Transcoders");

A quick fix is to modify the first 'if' statement so it appears as below.
This will make the transcoder use the same profile it would use for
'autodetect mpeg-2'.  Not a long-term fix, but something to get you working.

        if (encodingType == "MPEG-2" || encodingType == "H.264")
            result = profile.loadByGroup("MPEG2", "Transcoders");
        if (encodingType == "MPEG-4" || encodingType == "RTjpeg")
            result = profile.loadByGroup("RTjpeg/MPEG4",
                                         "Transcoders");

We should add a separate set of profiles for H.264 at some point.
