The resizing to 720p itself, although a little different compared to the approach used for VobSub, would be easy to implement. Then again, I don't have any SUP writing functionality yet (as well as SUB/IDX Reading). While one might think that it should be easy to implement a writer when you already know the format to implement a reader, the problem is that I can skip a lot of unknown stuff when reading, but have to write it when writing.
Chances are that with all the guessing about these unknown fields I have to do, the written SUP file creates all kind of problems when used with different players.
