I already have an E80 and am think of getting a E85 also. Do the remotes use the same frequency? Ie, will the power button on the e85 also affect the e80? I know my vcr remote has 2 buttons on it so you can use the same remote for 2 vcrs but you can select which one to use (vcr-a,b). I'm don't really care if I have to use 2 remotes, I'm more concerned about using the remote for 1 and having it affect the other (especially a power or stop button). Also could I stack them on top of each other or would heat be an issue. Basically, the 2nd recorder is mainly for time shifting recording. I thought for $450 for the E85, tat's is competitive with a tivo after paying a full subscription (I know tivo has more features, but not sure if I need them.
