"Tune to channel" feature/reminder

[Torque]

A cool feature I have with my Dish Network box is a scheduler that allows me to set a reminder/auto tune for a show.  

For example, I'm looking through the guide and I see 'NYPD Blue' will be on channel 31 at 6pm.  I highlite that show and tell it to "Remind me" to change to this channel five minutes before it comes on.  So then I go back to channel 7 and watch some other show.  At 5:55pm, a little note at the bottom of the screen says "NYPD blue will be starting in 5 minutes on Channel 31, do you want to change to this channel now? Ok/Cancel"  If I hit OK on the remote, it takes me to channel 31.  Hitting Cancel clears the message.  I think there's also a "remind me in 5 minutes" option too.

The auto tune works about the same way, but instead of popping up a note asking me to change to that channel, it just automatically does it.  

If either or both could be implemented, that would rock.  It doesn't need to record or go into time shift mode, just automatically change to that channel.
