Same here, and this is precisely the way I think it should work too. 
Record both AC3 and normal track, and then choose in the player. People 
might have multiple frontends, where one can handle AC3 and one can't. I 
just need to fix the PS recorder but thanks to Marcus' patches I think 
this should be pretty easy now.

I only get AC3 once in a while, but when I do it is sent in *addition* 
to a regular audio track.
