Couldn't agree more! DVDlab is incredible. The only thing it's missing is multiple audio tracks, which I wouldn't think would be difficult to implement, but the creator says it is in his FAQ.

I also wish the editing could be more accurate.

Anyway, it's funny you should mention it, I have a few DVD backups of Smallville as well, though they're only downloads and not Tivo recordings. I don't know why I like that show so much

By the way, what quality setting are you recording your shows that you want for backup, and did you adjust the settings through Tivoweb at all?
