Hi All - I have two DirecTV Tivos and both have the black peanut remote. One unit is a Philips DSR704 and the other is a DirecTV DVR R10. I need to replace the remotes as the buttons are getting worn and the battery covers are broke (and I don't want to tape them anymore, LOL). I was wondering how I tell which remote models they are. I keep seeing things like series 2 and stuff like that. Since the remotes are expensive, I want to make sure I get the correct ones. I hope someone can help! Thanks a bunch!
