I recently moved to a home that won't support DirecTV, so I've gotten the next best thing Comcast + TiVo. For the most part it's fine, but with this new setup my Samsung UN46D8000 no longer automatically switches into 3D mode as it did when I had the DirecTV HD DVR. I can manually switch it into the correct mode, but thats not ideal. Since this is the same TV, same HDMI cable is this because TiVo does not adequately support this feature, or is it due to the Comcast input?
I contacted TiVo support but they just blame my TV -
Thank you for contacting TiVo Customer Support. I would be glad to help you with your 3D issues today.
The TiVo Premiere does support MPEG-4 3D programming. This seems to be more of an output format issue on the TV end. Side by side 3D is a type of 3D (there are a plethora of different formats, just check any 3D YouTube video on your computer and it will give you about 5 options on how you would like to view the 3D).
I suggest putting on a 3D channel, your 3D glasses, and using your TV remote to toggle settings in the TV. Maybe select "side by side" viewing and see what happens. If that fails, I would actually suggest contacting your TV manufacturer support and have them walk you through the steps. If that fails, feel free to contact us back and we can continue helping you resolve your issue
