I had (wrongly) assumed that at the minimum the black bars would be clear and all alien languages would be a forced subtitle track.
I don't know why I thought that for a moment, but I did.
If you use DVD-rb or whatever else, even if they correctly identify the black borders and remove them (since there is text burned in there), you won't have captions.
Anamorphic conversion is going to take much more work to convert, starting with a newly timed caption track.
Sigh.
Anyone know how X0 plans on handling the subtitles?
