Are you saying that DVD does subtitling by lossless graphics, rather
than, say, Unicode? I wondered why the font changes so often. I guess it
makes sense, as it keeps the handling of thing like Devanagiri as easy
as Romance text. Highly flexible for karaoke too (much bigger market
than anything remotely educational).
