I got the Premiere XL as soon as it released, and like many others here was severely disappointed in its sluggish performance. When the 2.x update finally came out it seemed to be a big improvement for the speed of the menus, but that speed didn't seem to last. Starting some months after I got the 2.x update I started noticing long delays again, and this time it also impacted SD menus as well as HD menus. My frustration had been building when I got my new iPad 3 and decided to try the Tivo remote program that was in the iPad app store: no delays or slowness at all. I was stunned, so I tried replacing the batteries in the remote to see if that helped, but it didn't seem to. I started to pay attention to what was going on with the remote and noticed that quite a few times I had to press the buttons just a certain way for them to work, or repeatedly press them. I decided to try the slide out qwerty keyboard remote so I picked one up from Best Buy and hooked up the blue tooth connection on it. The performance is a complete 180, my Tivo is now snappy even in HD menus and the entire thing is now performing as I would expect a $500 appliance to perform. Besides the obvious thought that the remote that came with the Premiere had started to die (my old S2 remote lasted 6 years without any problems so I never suspected this new standard remote), I also wonder if it isn't related to using infrared for control. I'm going to remove the USB blue tooth connector and try the new remote in infrared mode to see if I notice a difference.
