Comment (by mikep@…):

 Maybe this will be helpful. When I record one of the Music Choice
 channels, Myth makes a small file, like 376 bytes. That file sits there
 for like 30 seconds or a minute, at least. Then, after that period, it
 starts getting larger like a normal recording.

 If I play a recording that didn't go long enough to start getting larger,
 I get an error: "Could not read first 2048 bytes". If I wait until the
 recording is getting larger before stopping it, Myth will play the file
 successfully.

 I think there is something in the stream that MythTV is looking for that
 isn't sent down within a certain number of seconds, so Myth will time out
 in live tv mode. In recording mode, it basically waits for the data it
 needs to see before starting to put data into the recording.

 I will try to upload both one of the 376 byte files and a file after the
 recording is playable. For what it's worth, VLC will play the stream
 starting immediately, without waiting for whatever it is that Myth is
 waiting for before putting good data into the recording file.

 Edit: I uploaded a successful recording, which Myth still seems to have
 some trouble playing. It sounds like it skips a lot, although there is at
 least some sound and a video background. It seems like there is only sound
 right around when the image changes, then it skips to when the next video
 update happens?

 I was unable to upload a bad file, as Myth deletes it if I stop the
 recording within 30 seconds or a minute. If I try to play the recording
 within 10 or 20 seconds of starting it (but while it is still recording),
 I get a message that the recording isn't ready yet. I am able to start
 playing recordings of normal video channels within a second or two of
 starting the recording, so this seems to be a result of myth not having
 recorded any data yet.
