Weak batteries in your remote control? Are you "aiming" the remote control at your TV, when you should be aiming at the Shaw PVR (except when changing the TV's volume).
I'm having the same issue and i've replaced the batteries.
I'll hit the shaw button to go to the blue curve menus, it takes 10-15s for any response. Then takes another 10s or so to load just the basic menu.
I'll arrow over and hit enter to go to my saved/pvrd shows. Again, taking a long time to respond to my button presses. And even when the system does respond, it takes a long time to load the next menu when I switch menus. My experience tells me it's not likely a remote issue, but something to do with the box/system.
I've also tried swapping the batteries from the remote in my other room. Still same issue. The menus/responsiveness is fine on my other TV.
No, the remotes are not interchangeable. I could possibly look up how to reprogram them but I am pretty sure at this point it's not a remote issue.
@cmauthe -- no luck
Got a friend with the same BlueCurve remote-control, who will bring it to your home?
It should mostly work: Guide, Menu, Channel Up/Down, Play/Pause, et cetera -- but not Volume Up/Down/Mute.
Does that remote-control cause the BlueCurve to respond more quickly than your remote-control?
