The biggest problem is that each session starts out with good quality, but it then deteriorates. It will sometimes stall completely, usually during commercial breaks. I've taken to killing, then restarting the browser during each commercial break. It really is a PITA. This involves having a wireless mouse and keyboard along with the TV AND Cable remote (all four are required). The commercial breaks also seem endless. Most of the commercial time is dead picture and sound. It really seems stupid siting in your living room watching absolutely nothing on the TV. There is an occasional commercial which is way louder than the program, and the same 4 or 5 commercials repeat over, and over, and over, and .......
It isn’t always freezing during commercials, it is just showing a blank screen. That is actually when the networks allow the cable companies to insert their commercials.
