Easy way/product to convert flv to tivo format?

Hello all,



I'm interested in converting an existing .flv video that I have from the web into a format that I can use with my Tivo (I have a Premiere and a Romaio).



Most of the google searches seem to indicate that a product called Videora made a Tivo converter - I downloaded that; but it really only works with AVI to Tivo -- not flv.



Is there any product that will help with this conversion?



Thanks so much!
