Yeah, I read that Harmy said it would. I was just sort of continuing the conversation.

The issue for me really seems to be specifically with Bluray subtitles (PGS) when converting to MKV. DVD subs would work fine.

DVD subs would function, but they would have lots of aliasing compared to PGS, due to not enough colors/alpha to do curves and diagonals. I've done DVD subs for one of Chewtobacca's DVD projects, and while I think they look as good as DVD subs can look, they don't really fool anyone about being original theatrical subs. To sharp, too defined, too regular, too aliased. Burnt-in would have been better.
