Streaming non- HD from Netflix through TiVo works okay. However, with HD you get sound and only a gray screen. This is been tried with multiple programs with the same result so it does not appear to be related to any individual Netflix program. We tried changing out the wireless connection to the TiVo for a cat 5 cable no change. The TiVo is connected via HDMI to a Yamaha RXV-1900 receiver and on to a Sony TV via another HDMI cable. (By the way, the TV shows the resolution of 720 P HD.) The Netflix people suggest that maybe there's some copy protection thing going on at the receiver side that is blanking out the picture, and that maybe by routing the TiVo to the TV and back to the receiver (which would be a mess) might help. Anyway, if anyone has any suggestions or experience with this type of situation to offer, it will be most appreciated! This is a very frustrating problem. Many thanks!
