amixer -c <card n>?
alsamixer -c n?

Try muting your CD input and using it as the recording input. You need
the sound to get recorded with the video so when Myth plays it back it
is playing the sound from the recording not the sound from the TV card
which is at a completely different time in the AV stream.
