hi, i just got hooked up w/ charter and got the Motorola DCX3501-M DVR w/ 2 tuners. I just had DirecTV. their 2 tuner DVR allowed you to switch between tuners so you can view 2 separate channels without losing the buffering of either channel. so when you swap to the other tuner, you can go back, forward, pause, etc. i called support for charter and they say you can't do that w/ this DVR. is this true? i certainly hope not. it doesn't matter whether you are recording one program, two programs or none. thanks in advance.
