I had assumed this was due to some problem with CAM keys from the provider 
expiring, or something.  I still intermittantly get "channel not available", 
but haven't found any way to recreate the problem at will.

I also occasionally have a CAM crash - where the status in goes from 
"ALPHACRYPT" to "CAM PRESENT" or "CAM READY".  A manual reset (or multiple) 
fixes this, but I get no decryption during a "crash".

...problems I've had to live with for months.  Gave up asking and installed 
an FTA satellite dish for 50% of my mostly watched channels.
