BTW - for those of you having issues with 3D detection, here's what I can offer:
I have a 50' (yes 50') HDMI cable (GE brand, nothing special, was around $25 I believe) running into my Pioneer 1021 receiver, and from there a 6' cheap (Sam's Club) HDMI cable into the Panasonic 210 Blue Ray (as well as another 6' from the receiver to the XBox 360).
I have NO issues with the projector set on AUTO with it detecting and syncing 3d. And never have. In fact, at first I was running the 50' HDMI into an HDMI wall jack, from there with a 6' HDMI cable (virtually same as others I use) into the receiver, and then from the receiver into a 6' HDMI cable into the devices. So at least 62' run, not including what's done inside the receiver.
One exception to that is sometimes the Panasonic player will state that its not connected to a 3D source. Though that it easily solvable by turning off the receiver and back on. (perhaps a receiver or BR sync issue). Immediately it detects the 3D source and works (again with PJ set to Auto). NEVER happened when I had a Sony 3D BR player at all. I've only seen this happen when I've watched a movie (in 2D) immediately prior. Not sure if its heat related on the Panny BR or if something is getting signaling confused.
The Panny has a few quirks I've noticed (locks up in NetFlix from time to time, in NetFlix sometimes switches to lower quality than it should (tons of bandwidth, this isn't the issue) in mid movie, in NetFlix sometimes sound isn't synced right (not sure why), and has locked up twice in the middle of playing a BRAND NEW Blue Ray disk (had to power off player). Wish I had kept the Sony. (other than my coupon for 3D Avatar).
One thing I do like about the Panny though it that it allows for adjustment of 3D depth, which really helps to get rid of 3d Crosstalk (Alice in Wonderland 3D (Johnny Depp) on the menu has some ghosting/cross talk until I set this). Seems that for Epson glasses a -3 setting works best, for the Sony Playstation 3D glasses (which work great with the 3010), -2 is best. -2 works great on Epson glasses too, so that's where I leave it.
Anyways, just wanted to throw out in my case I have no real auto 3D detection issues, even with my less than optimal cable setting. I was all prepared to buy a powered 35' HDMI cable as I was expecting problems, but the El Cheapo cable works great for me, even through the receiver.
2D-3D conversion on the Panny I admit isn't great, but it does take 2D movies that almost look 3D (like Avatar in 2D and Return of the King) and makes some scenes TRULY look 3D at least for some of the things in the picture (ie: castle siege on ROTK with the battering ram and trolls looks very good here). So it basically only can enhance an already "3d-ish" 2D image from what I've seen. (I've seen a couple of "3D" movies that were converted by the studio poorly that the 2D-3D conversion on the Panny actually looks better). But you'll get no WHERE near the quality of a well done 3D movie with this conversion (Beauty and the Beast is excellent BTW)).
