Comment:

 I should also note that the word "certain" is important. The audio from
 the recording of one film from Turner Classic Movies will be fine, while
 the recording of the next film on the channel will have the audio issue.
 It's not the (pre-Dolby and usually pre-stereo) movies themselves;
 typically both affected and unaffected recordings starts with TCM's own
 commercials in between the recordings. If the audio issue exists at the
 beginning of the recording, it will affect the entire recording;
 otherwise, no problems. Since the audio issue also exists when playing the
 affected recordings through mplayer, I must assume that it has something
 to do with the FireWire recording portion of mythbackend, as opposed to
 mythfrontend's audio-decoding code. I have changed the Summary line
 accordingly.

 PS: In case it's not clear, "basic cable channel" = analog cable channels,
 which on my system and on most others' are those under 100. 100 and above
 mark digital cable channels.
