FWIW, and I'm not sure this is at all helpful---
I'm running a very old version of Myth (0.18.1). That version garbles
CC output by (apparently) swapping a few letters around (looks almost
like a middle-endian sort of swap), but ONLY IF what I'm displaying is
NOT from Live-TV, and ONLY IF the machine has never displayed Live-TV
since warm- or cold-boot. (I'm using the television's built-in CC1
decoder to display these captions, btw, not anything that Myth can do
to generate the characters themselves. And I dump CC data into files
from what I record, and -that's- always correct, so it seems specifically
related to what Myth is giving the 350, or how the 350 is interpreting it.)
[ivtv 0.4.0 and ivtv 0.4.1, btw, and kernel 2.6.12. Yes, I said old.]
In other words, displaying any channel in Live-TV fixes the CC-display
problem instantly (Live-TV never looks wrong, and non-Live-TV suddenly
looks right) until the next reboot.
Since you say your Live-TV is okay, this is presumably not the problem,
but it's clear that at least in old versions of Myth, -something- gets
initialized differently between the two modes. Now, a TON of things
have changed since (including dropping the LiveTV ringbuffer completely)
and I haven't bug-reported this behavior because 0.18.1 was old enough
that it wasn't worth it at the time and none of the devos even have a
350, so I despaired of any action being taken even if I did. (I figured
I'd complain if the current version still did it, once I transition to it.)
But you might want to at least keep track of what you've done since boot
in case there is state somewhere that's getting preserved.
Something I've never tried, but you might---does playing things back
using mplayer (e.g., not using Myth at all) show captioning? Is it
garbled?
