3D Via Cable vs BluRay

I am a little confused here. I just purchased a 3D bundle (TV, extra glasses, 3D Blu-Ray player) though they were currently out of the 3D blu ray players so I am waiting for that to come in.

I set everything up when I arrived home, and for anxious experimentation I thought I would try some 3D content that Comcast provided.

Now for the setup: I run COMPONENT (NOT HDMI) cables from my cable box to my Hauppauge PVR. From the PVR I run COMPONENT cables to my 6 year old HDMI 1.1 era receiver. From the receiver I run what is probably also a HDMI 1.1 cable to the TV (I ordered some 1.4a's from Amazon that are on the way). To my surprise, the 3D worked flawlessly! Not only is it basically running just off component cable signals, the HDMI is definitely not up to 3D standards, and the receiver most certainly does not boast 3D pass through.

Now with that being said, WHY does the Blu-Ray player AND receiver need to be upgraded to watch 3D BD? It seems to me that it is a waste of $$ to have to upgrade all your equipment, when I have shown that you can run 3D straight from good old fashioned compononet cables.

less resolution man.

sequential 3D sends two 1080p images at once down the hdmi wire. You are probably doing 480p or something like that (two 480p or two 540p).

But if you can't see the difference then don't worry about it.

What TV do you have? If it is a Samsung, it is most likely doing a 2D to 3D conversion for you, which is not optimal.

It's a Panasonic plasma. The resolution thing makes sense now, it is a top/bottm mode for cable. It still looks pretty much in HD to me though.

I really don't plan to watch more than a movie or two in 3D a month really at most (probably less than that), but it was such a nice 2D TV and nice to have the 3D option. It will be nice to actually get the blu-ray player and see what the difference is - hopefully it won't take too long. It is the end of the model season so I am guessing it just may end up being a newer model if the old ones don't come in again.

Blu-ray uses a method called Frame Packing that actually puts two 1920x1080 images in one frame (with a small buffer).

From what I've read, most receivers can still handle the passing of the video; however, the audio cannot be extracted because it's not in the same position.
