I've recently hit similar problems with the test DTT system here in NZ as
they are using H.264 and AAC audio.

You will need to patch the file scan.c to detect the H.264 and AAC audio
streams as being valid. I'll be submitting patched back to this list later
today that allow that.

Also in order to get mplayer to work you will need to add the PID of the
channels PMT entry to the video pid in channels.conf

EG if the channel has aPID 107 vPid 109 and PMT of 100 it will have
entries like

Name:.... Other Tuning Data....:109+100:107:

This tells mplayer to look at both the vPID and the PMT data from which it
realizes the stream is H.264.
