Let the hive mind of Engadget get that for you.
"I'm looking for a wireless trackpad to use with my older (2.5 or so years old) C2D MacBook that's perpetually docked to my home theater. Something sleek, thin, not too small, made of high quality materials. Ideally, it would natively support all of (Snow) Leopard's multitouch inputs, and even more ideally, it would have a charging dock / base. The only problem is that I'm not sure that such a thing even exists. Think you can throw me a bone?"
Just think Dish Network has only had this feture for some year now.....
WHAT you say? Let me explane, all you need is a Dish Network 522 or above DULE Tuner system setup in single mode. you watch the football game on you TV with tuner #1 and record it with tuner #2, then if you want to rewind a section while still watching live tv you jst pop up a PIP window and rewind tuner #2 in it and BOOM you got live tv with a PIP rewind window.
