First off, I'm only interested in the basic subtitles you see when watching a standard Hollywood movie in English that has some scenes in another language with subtitles. The ones you don't have to turn on they just show up as part of the movie. Not closed captioning for hearing impaired - where it tells you more than dialog like "music is heard" or "a rooster crows in the distance" and you get a big black rectangle on your screen that you can't see through.

What I don't get is, why if I have an MPG file that I play with a DVD player or MS Media Player on my PC, I see subtitles. If I transfer it to Tivo I do not see the sub-titles.

I think I've read that Tivo does not support that but...then why if I rent a movie from Amazon Unbox, do I see the subtitles without any issues?

Thanks for any help or knowledge.

There are two types of subtitles. Either directly "baked" into the video or superimposed at time of playback from another or stream within the movie.

When you see the subtitles for foreign/alien languages in an otherwise English movie, those are normally baked directly into the video.

DVD movies with subtitle tracks superimpose them instead.

If I remember correctly, for the Tivo to do superimposed subtitles, the subs have to be coded into a non-visible region of the video above the picture. There aren't that many tools to do so. Someone wrote t2sami to do it on a Windows machine, but integrating it into pyTivo hasn't been discussed recently that I can tell.

Thank you for the response. I believe I only want the "baked in" subtitles.

E.g. Letters from Iwo Jima (all Japenese with baked in English subtitles I think.)

The vob/mpg file I've created shows the subtitles in MS Media Player but when I move the file to the tivo the subtitles disappear. This happens with any files I create.

Has anyone been able to rip any DVD files with "baked in" subtitles and have them appear when playing back through Tivo?

Thanks.

Sounds like your mpg file doesn't really have "baked in" subtitles. "baked in" means that it is part of the video and therefore will be displayed on the Tivo.

Your mpg file probably has an subtitle stream. If you run ffmpeg -i <filename> it will probably list a third stream with the subtitles in it. pyTivo doesn't deal with subtitle streams.

You can use mplayer with some options to "bake" the subtitles into the video creating a new mpg file you can then send to the Tivo with pyTivo.
