Re: Couple questions about the filter...

Yeah, I just looked up the interfaces I had to use and took it from
there. I never thought I'd say this, but thank God for Microsoft and
their documentation.

For the audio, I'm gonna try connecting the two pins directly...for
video DirectShow builds any intermediate filters you need so I'm hoping
they'll do the same for audio. If not, I'll check the AVI file somehow.

What I'll probably do is just query for the interface...I really like
the batch conversion feature and don't want to give it up. Do you know
which interface to use? I saw IMediaPropertyBag and just plain old
IPropertyBag, but I'm not too sure which to use.

Oh, I got the updated filter, thanks.
