I just went out to Dish TV in Hamilton and bought the gen 3 remote for $35.00
It definatly makes a difference, you don't have to use it like a rifle sight as I had to do with the original remote that came with the T2200.
The buttons are larger with more spacing and make a clicking sound as well so you know it been pushed.
Its made the controls a lot more positive now as the IR field on the top of the remote is 30mm wide.
I think that most of the lag problems are coming from the tiny buttons and the narrow IR field on the original remotes.
Its something that Dish TV should replace with the the T2200 boxes being sold as everyone has always complained about dish TV remotes, they might sell a lot more to ex Tivo owners as well :)
