From what I've been reading on the net is that the product is good, but their customer service blows ass.
I'm also trying to figure out if it would be best to put the slingbox on a DVR that's in room that is hardly used. My chinese boyfriend here said that when you're watching tv over the slingbox you see exactly what's playing on the cable box back home. If you change the channel, it changes the channel on the tv back home.
Haven't found anything that says "yes" or "no" on that front.
