Great, but one fix needed
The only problem I have with this app is: it starts off vertical format with the TV image small, in the top half of the screen. It is supposed to go to full screen when it is turned on its side--horizontal. It takes a long time to get it to do that, and I have to switch the orientation back and forth a number of times. Often it will only go horizontal if held on the left side up. Sometimes it wont orient horizontally at all. This was not problem prior to the last update. They fix one bug and another pops up!
