I change the channels with an IR Blaster since I have a Scientific Atlanta STB. When I tune in to LiveTV for the first time I don't have any problems, When I change the channel, I usually end up having a problem on the first channel change with the screen going black with audio. Sometimes it will change okay multiple times but eventually the screen will go black on a channel change. I've attached logs. In the log, the black screen occurred on the fourth channel change.
