kmttg & iTunes Tags on a Mac

Anyone have a suggestion on the best tool for modifying the sometime (or most time) messed up meta tags that kmttg gets from TiVo?

Looking for something that uses what kmttg produces to find a 'best' match from the web, and populates them.

I have been using iDentify which is good, but still struggle with cleaning them up so that they can be fully cleaned up.

Thank you
