ReplayTV RTV5516 160-Hour Digital Video Recorder
Don't know about Tivo but Replay TV is not worth the $$$
Bought Replay TV from Amazon. Set it up when it was delivered. Set up was easy. But programing the unit and getting it ready to use was an excersize in frustration. First it would not network with my home network so it could not program thru the internet. Called tech support (not India, thank god) after working with the rep for over an hour finally got it programed (more later). Then shows that were recorded with Replay would  randomly flucuate in sound output, from god turn it off, to I have my ear on the speaker and I still can't hear it. Called tech support again, they could not figure it out. Then the unit would quit accepting signal input from the cable. All the other TVs in the house never lost siganl. Tech support again, again no help. Then the unit stopped connecting out to Replay TV servers and would not update. Tired of talking to tech support. Sent the unit back to Amazon (at my expense). I had it less then 3 days. Maybe you will be luckier, but I won't try Replay TV again. I should have listened to my brother and got a Tivo.
