Video Editing?

[PVR]

Hi everyone,

I am able to extract video from my tivo using extractstream and tivoapp.

Can anyone tell me how to edit these files? I know that if I bring them over as mpeg, I would have to use an mpeg2 editor.

How would I edit them in tystream format and how do I convert them to other formats?

Is there a web page with some Tytools?

I use a Mac to do high-end video editing, so it would be nice to get them on the mac for editing in Final Cut Pro, DVD Studio, Imovie, etc.

Thanks!
