i love my replaytv. i don't know why anyone would ever watch live tv. it just ain't natural. we've had ours for several years. we very quickly grew out of the original 20 gig hard drive. so i followed the internet instructions and added a second 60 gig hard drive. woo hooty. except it was a noisy quantum fireball. it didn't take long to show up with some problems. like freezing while playing. pah. and it's been getting worse. now it pretty much won't play anything. i revisited the internet and found i can upgrade using the mac. yay! so now it has a very quiet 120 gig hard drive. double yay.
