I just got a new TiVo, set up my sub, etc. Watched and recorded a couple of things and all was good.
Next I tried to watch a Youtube video. I found the one I wanted to see, selected it and it showed the control bar (pause, ff, rew, etc.) at the bottom of the screen, then the screen went blank. I hit one of the buttons and the control bar appeared again and I could see that the elapsed time of the video was progressing and the progress bar of both what's played and what's been downloaded were being updated, but still no picture or sound.
I tried this with several different videos but always the same thing. TiVo support hasn't been any help. Has anyone else seen something like this?
