I have been an avid TiVo user for many many years, and am a power user. I have been on these forums for ages.
Over the course of time, I have attempted on several occasions with making better use of Closed Captioning.
Here is what I do know.
TiVo records the shows off cable/ota and does encode the CC track, as when we watch the our recording, we can in fact turn on or off the CC track as needed.
The problems come now from when you move the show from your TiVo to your computer or now NAS device. Using either TD+ or pyTiVo, or in my case, the firmware part of the Netgear NAS that pulls the show off the TiVo.
Then of course transfering the show back to the TiVo for viewing again.
It seems when a TiVo file undergoes this process. The CC sometimes but not always gets lost or becomes unuseable.
TD+ I have noticed if you let it pull the TiVo file, and then transfer it back, and never messed with the .TiVo file. It will retain the CC. If however you converted it to MPG, or anything else, and then allow TD+ to transfer it back. The CC is lost.
PyTiVo doesn't seem to preserve the CC information, even if I keep the file a .TiVo file. maybe I have a setting wrong?
The Netgear NAS, Sadly for some reason, the CC will will get lost on some files, and some it won't. Haven't figured that one out yet.
It doesn't seem that if I have other video files that never orginated on the TiVo that using subtitles/CC is near to imposible to get to work with TD+ or pyTiVo currently without just hardcoding the subtitles into the original video file to begin with. Apparently their is no way to convert subtitle files into CC files and to encode the video stream to the TiVo as an actual CC stream that can be turned on or off by the TiVo.
Am I correct in this thinking? That currently there is not any inexpensive way to encode a file in advance of sending the stream to the TiVo or at the time it is being streamed to the TiVo in CC format so that the TiVo can turn on or turn off the CC stream?
I do understand that CC is encoded, displayed differently than subtitles are with DVD's/Blu-rays/MKV files etc...
