Also, AFAIK (please correct me if I'm wrong), Toast only allows transfer *AND* conversion to another format (e.g. iPad) combination.. So you're in for very long transfers. Also, I don't think it allows any editing either.
So unfortunately, using kmttg + something like MPEG Streamclip (good editing ability, doesn't work with all shows) + for SOME shows mplayer and/or VLC (both play basically anything, they have horrible editing functionality) are what you've got.. But they're all free.
I'd gladly pay for a Mac product if it (1) transferred to/from a Mac, and (2) played EVERYTHING I could get off of a Tivo, AND (3) had good raw MPEG-2 editing (as good as my standalone XS32 recorder has).
