I'm pretty sure that the TiVo actually strips the CC signal out before mpeg2 encoding the video. I seem to recall reading that the text gets stored as a parsable text file. Then it reinserts the CC info after decoding the file. Otherwise the mpeg2 compression would likely corrupt the CC info.

So the TiVo is messing with the CC signal. However, it is always doing so, even in the "live" buffer. Which is why the original poster's problem is so confusing, because their shouldn't be any way for the TiVos CC functionality to be different between "live" and recorded since both are recorded. (Unless you bypass the TiVo or put it in standby).

This issue occurred on older version (I'm lost with all those verisions now...) and DirecTV managed to fix the problem with version 3.1.1. This explicitly proves that CC and picture are NOT recorded together.

With the 6.1 update, they "broke" the CC again.

The problem lies in how the video is played back (I'm not an expert in audio-visual component), I know it doesn't make sense because the video is "buffered" but, whenever I go back in the buffer or watch a previously recorded show, captions suddenly go out of sync. When I catch up with the buffer and start watching it "live" and then it goes back into sync.

Yep. And the fact of the behavior you are observing trumps the theory that "live" or behind in the buffer shouldn't behave differently for CC.

I do wonder what they did that made that difference, but I don't doubt that you and a few others have seen the behavior you are describing.

It's irritating when CC is messed up. I was watching something recently, where the next line that should be after a long pause in talking would mistakenly pop up at the start of the pause, and then hang on screen until the next line. Sometimes it was up there for over 15 seconds as the show would be doing scene changes, musical stuff, etc. Very annoying.
