I am looking to repair/upgrade my Series 3 Tivo (TCD648250B). I see an ebay auction for someone selling what appears to be a TiVo upgrade kit of some kind (ebay item #220921578660). A statement in the auction claims its "far superior to instant cake". I'm trying to figure out if this is actual software included or if they are simply giving you instructions on how to maybe use free stuff out there (like WinMFS). I'm thinking probably the later, but figured I would ask here to see if anyone is familiar with this seller/product. Their rating is 100% positive feedback so while they might be legit, I'm just trying to figure out what they are exactly selling.
