Hello I just added a TivoHD as an addition to my S3. However I am having a problem with it. Occasionly when I turn the Tivo on, I see a gray screen and nothing else. I can press the Tivo button and I do see the main menu. If I try to play a recorded video it just gets stuck on the "Play now" screen. If I press 'Live TV' on the remote it goes to a gray screen and doesnt play anything. No video/audio. Only way to resolve the issue is to reboot the unit. Which I can do through the menu. Firmware version is 8.1.7c. Any ideas?
