Don’t upgrade so fast. I received the 7.3.1 this morning and my tivo is acting so slow. the guide data fills in like a tetris game. i called tivo and they said they know about the problem. I asked them why they allowed me to download software this morning they knew was bad and they had no answer execpt they may fix it in a week. Boo Tivo, Boo
Just talked to tech support. They said that their engineers are working to find the cause of the problem and once they do an upgrade will be distributed. No ETA was given. Bummer.
