Yeah the old one wouldn't have enough buttons.

I haven't seen a replay remote.

I need about 17 for all the stuff I use on the tivo remote.

30 sec skip
Tivo button
4 buttons to replace the four way thing
play
pause
record
2 for vol
2 for channel
enter
live / guide
tv power
mute

I'm not sure if it's worth giving up using the tivo remote for the convience of being able to use one for everything or not I haven't decieded yet. I wish a store would carry these things.
