I gave the X1 a try about 2 months ago. I liked the system, my wife did not. When Comcast first put it in, I had trouble gettingNHL Center Ice games in HD. After going back and forth with Comcast, it was finally fixed. but then, other trouble popped up. Sometimes the channel you were on would freeze up and you couldn't change channels. I would pull the plug and reboot the affected box and sometimes that worked, sometimes not. One night, all the boxes were affected and it took a few hours before it all went back to normal. The issue with Center Ice was if you turned on the HD channel for a hockey game, a window would pop up saying HD wasn't available, then would send you to a totally different channel. My wife doesn't care about whether a channel is HD or SD, she just watches. She didn't like it when you would go to a channel, then a window would pop up saying it found the HD equivalent and it would send you to that HD channel version. So after about a month, I decided to switch back to the regular cable tv and that's fine. It all works better.
