I ordered and received the Under The Sea 3D Blu-ray from WOWHD.
The disc was delivered in an envelope from Hong Kong.
It states that it's 3D Blu-ray on both the package and right on the disc label itself.
But it won't play in 3D. In fact it plays in 2D only and in the menu there's no choice of 3D or 2D.
All my other 3D discs play fine on my Samsung TV and 3D blu-ray player.

Is there a way to see if the disc is really 3D or not? Are 3Ds a different file format compared to 2D perhaps?

Most 3D discs will be Blu-Ray, not DVD. Yes, the file format is different for 3D than for 2D. If you download Stereoscopic Player (free trial version) for your PC and run your disc through your PC with your 3D display hooked up to it, you might be able to see what kind of 3D your DVD has on it.

Some of the 3D file formats look the same as 2D formats when you look at their file names in a directory. Examples of those would be side-by-side, top-bottom, and interleaved. Those would also be the most likely ones to be on a DVD, so viewing it through Stereoscopic Player would probably be the easiest way to find and use the particular 3D format used.

Or, maybe your DVD has an anaglyph 3D format which uses the colored glasses. That would not utilize the 3D display for 3D - it would work as well as it can work on any kind of color display.

The 3D on Blu-Ray disks has a different format from 2D, and you can identify that by looking at the files in the directory, if you know what to look for. Almost surely, a DVD would not have that frame packed file format, though, as there would not be enough room on a DVD for very many minutes of 3D video in that format.

3D BDs are encoded using the AVC MVC codec

Does the disk have the official Blu-Ray 3D logo on it?
See:

Yes, it has the official Logo.
I borrowed a friend's copy and it looks exactly the same. His works perfectly.

Sort of a bit bothersome that even though one buys a product from one's own country the product and the customer service are all from overseas.
I have to ship the disc back to China.
They'll credit me the shipping charges.

having an official logo "printed" on the disc does not make it legit...

This. Your disc sounds like a bootleg done in DVD format or on BD, but without the 3D-format files.

I believe they were referring to high definition 3D.  SbS 3D is two half frames (960x1080) squeezed into one.  Half the lines for each eye are thrown away to make it work.  The same can be done for SD on a DVD, but the resolution is even lower.

 

Bluyray3D is two full 1920x1080 frames packed into a special frame size not compatible with DVD.  Each eye sees its own individual full 1920x1080 image.

ok yes that makes more sense but to be honest im perfectly fine with the sbs and saving 25-40 per one disc. its hd and picture is perfect/clear. Question for you what is the correct term for the full 1920x1080 version full sbs?!?!? But either way good deal just send the disc back and cop another copy

Full SBS is often called 1080p Frame sequential or 1080p page skipping. Half Sbs is known as HDMI1.4a 1080i sbs.

Maximum resolution possible with DVD is 720×480/720×576 (480i/576i) 9.8Mbps, which is NOT HD.  You then divide that in half when you compress to SbS.

Trust me (one of my favorite internet sayings biggrin.gif) a 1/2 resolution DVD image would not be "smashing" in any stretch to me or >98% of the people on this forum. You must have a small TV and sit far (several screen widths) back to consider a DVD image "not dull in anyway" compared to a BD.eek.gif

Yet in this thread, you claim you sold your big screen TV because the picture was crap. rolleyes.gif http://www.avsforum.com/t/1414861/which-one-matters-most-the-tv-the-bluray-player-or-the-movie-itself#post_22121406

That's why HD is preferred. SD looks like crap on big screens, especially when you cut the resolution even more, as you are doing..

Sorry for assuming. It was all that talk of standarf def 3D. How long did you own the DLP? When did you buy it? How long have you had the 80LE632U?

about two months on the sharp for the theater room and not setup just hung on wall plan on doing something nice in there once i come up with ideals the mistu i had for about 3 months or so got it last year in aug-sept again no doubt if i played with it more and more im sure i could have improved the picture just have to gain that much more knowledge working on gettnig some 70" for the living room downstairs i want a basic 3d model might even settle for the 120hz model but im wondering if the 3d viewing will suffer as i have a 600hz lg im using and absolutely perfect i would like to see the same movie playing since they both are active of course and see if its rough or just the same or decient on a lower hz tv. I have read opinions on the topic of hz and 3d but nothing like seeing it with your own eyes smile.gif
