As most of you know I received a ROKU XS for Christmas and have been using it daily. This afternoon while still home sick I was adding some additional channels when all of a sudden I heard a "pop" and the TV went dark. When the TV rebooted ROKU was rebooting as well and a very large green horizontal line appeared at the bottom of the screen. When I switched to the Dish Network input a large yellow horizontal line appeared at the bottom of the screen. I almost had a heart attack thinking my new 50" LED TV had been damaged by the ROKU streaming device. I then powered down the TV and turned it back on resulting in the horizontal line being gone. My heart started beating again. Then about an hour later while "moving" a channel logo on the main GUI the ROKU rebooted again. I then used it for an additional 5 or more hours with no problems. Has anyone ever experienced any problems using their ROKU streaming devices? I worry due to it's small size that it doesn't have the protection circuitry needed. PS: I also noticed that HULU and Netflix produce a slightly better picture quality using one of my blu-ray players. However, perhaps it's just my imagination.
