Excellent news ! I always wondered why they just all of a sudden stopped 
working... probably some change that i made... but i wasn't sure what.

As to the encoder... is the reason that it only outputs to AVI, that it 
converts to directshow time ? (And my muxer wants granule pos)

This was something i struggled with for a while... i really wanted to just 
pass directshow times throughtout all the graph... but because theora 
actually has other information embedded in it's granule pos, if you convert 
it to a directshow time, you can't recover that information. So i ended up 
deciding to pass granule pos everywhere, and leave the responsibility to any 
filter that connects to a filter outside my little ecosystem to make the 
conversion.

Zen.
