There have been several times when I need to find a channel on my DirecTV service but I have no idea what the channel number is.  I would love to know about a search by name of the channel function where I could enter in 'D' for example and be taken to Disney Channel, Discovery Channel, etc.  Is there anything like this that exists for TiVos? 

I know that I can set up favorite channels and search that way, but usually the channels that I want aren't necessarily my "favorites".

Any help would be appreciated!
