I resently re imaged to 1.5 3 weeks ago and have had issues with the remote control failing.

Like this morning watching the super 14 and fast forwarding all the boring bits, the control stopped being able to control the tivo, the light on the remote still works and it still controls the TV but Tivo fails to get any codes from it. the way out was to reboot. This has happend twice now on 1.5 where as before I never had this issue at all.

Any idears as to whats going on with the Tivo?
