Black screen when playing programs.

My Romeo has been up for a week now and I'm beginning to see some strangeness. About one time in four when I start to play a recording I get a black screen. Nothing happens for four or five seconds then I get audio. I never do get video until I left arrow and start the recording again at which time it works perfectly.



Setup is hdmi to Vizio TV. Didn't have this problem with TiVo HD on hdmi and don't have it with xbmc running on raspberry pi.



Is anyone else seeing something similar?
