I've had my Roamio for a few weeks now and love it. I have had a reoccurring problem with the Motorola tuning adapter with it however: It seems that my Motorola tuning adapter is losing lock or signal but the light on the unit doesn't change to blinking. It's only until I switch to a channel that requires it's function do I realize it's not working properly. I've missed quiet a few recordings because of this. It used to happen once in a while on my XL4 as well, but it's happened 3-4 times already in the few weeks I've owned the Roamio. A simple restart of the TA usually fixes the problem. Sometimes though I need to restart both the TA and the Tivo to get it to lock back on again. I haven't quite figured out the magic of these stupid tuning adapters. One thing I have noticed that the Tivo is sending signals to the TA for EVERY SINGLE command. For example, if I change the volume on my receiver using the Tivo RF remote, the Tivo sends a signal to the TA (can tell because of the red status light). Maybe the TA is just getting too many signals and gets confused and looses lock. Even if I hit the Tivo button, the TA gets a signal. Like I said, basically everything I push on the RF remote, triggers the TA red light (meaning it's getting USB signal from the Tivo). Seems like that could be an issue? Perhaps I have a bad TA? Maybe a signal problem? Any ideas or suggestions would be appreciated. TA Specs: Motorola MTR-700 Platform Ver: 1.37 P.S. On another note, it seems as my TA is sometimes letting channels TIME OUT. Numerous times, I've turned on the TV to a black screen on a certain SDV channel. Once i switch the channel up and then down, it works fine, but it seems as though it's letting the channels time out even when one of the 6 tuners is currently tuned to that channel but not recording. Is that normal?
