Scrambled channel information streamed
I think many of has has ever came across situation, when channel playback didn't start, due to the missing descrambling information.
In this case it would be a nice feature if some image or short movie could be streamed in a loop. Instead of thinking why channel is not loading at all, users would see such information on their monitors and/or TV.
The example of such 'view' can be seen on this picture: http://img546.imageshack.us/img546/5403/10809380.jpg
It is not a priority, but very nice feature that i think many of us would like to see ;-)
