Hmm. It's not that young (SMIL 2.0 has been around for two and a half 
years with implementations, SMIL 1.0 for more than five) and not that 
badly implemented.

QuickTime and RealPlayer have both implemented it for a long time. I 
don't recall if Windows Media player does - that uses the simplified 
SAMI specification, which has some pretty serious gaps in functionality 
for serious accessibility. (It depends whether you mean providing sign 
language interpretation, captions and audio descriptions, and thinking 
about being able to give the right files according to the user's choice 
of player, as SMIL allows, or if you're just going to put basic 
captions, which SAMI can handle).

formats currently used, which will make life easier when it is

captioning video and generating quicktime/realplayer compatible content 
(it can also produce SAMI captions). I don't recall if it costs money
