I did this a couple of years ago and now can't seem to get it to work.
I followed all of the instructions in the help section and the "saving" window pops up for about 2 seconds and goes away and of course does not save. I am using TW4 Pro. I tried selecting all the different formats but none work.
Any suggestions?

Thought I would bump this back up. I'm still looking for the solution to the problem. I'm using TW5 pro now. It was suggested to download this codec http://www.free-codecs.com/download/ffdshow.htm but it does not seem to help either.
Thanks
