Channel 96 is hit and miss, even at the same resort. The only constant that I can relate in my experience is that each time I've had to punch in the number; it did not appear while scrolling through the channels.
Here's the recent history that I've experienced:
CBR - Barbados - October 08 - not working
CBR - North Trinidad - September 08 - working
Yacht Club - August 08 - working
POR, Magnolia Bend - June 08 - not working
CSR, Casitas 2 - April 08 - working
CSR, Casitas 3 - February 08 - working
CR - Garden Wing - September 06 - working
As you can see, no rhyme or reason. CBR was really odd and it was a trade-off, North Trinidad was an old room but had channel 96, Barbados was a new room, but no channel 96...
Hope this helps someone!
