Can Blu ray 3D be viewed on DVD player?

Q1:
I'm considering buying the above but i only have DVD player & a normal 2D
(HD) TV.  Can the video be viewed ?  

- No - both because the DVD player won't know how to handle the format of the BluRay disc and because your display needs to be 3D capable.

Q2:
Must my DVD player support NTSC/PAL to view the above video?  Or this is
irrelevant?

Irrelevant given the answer to 1

Note that most blue rays you buy will come with a 3d version and normal version (also called the rainbow pack).

It actually says Blu Ray 3d + blu Ray.  If you have just a normal DVD player though you still won't be able to view it.  

If you have a blu-ray player I would confirm with the seller if there are 2 discs.

> 2 discs
What's the purpose?  1 disc for 2D & 1 for 3D ?

I just got a set of 5 pcs of "Planet Earth" blu-ray discs :
all of them could be played on my DVD player & watched
on my 2D TV though I must say quality is not HD.

Curious if my blu ray discs are different in any way from
the ones Kyle have described

I was sure my player is an LG DVD player because when I bought it, it's
stated on the box it's a DVD player/recorder.  Looks like the Planet Earth
Bluray discs (as the plastic box that holds them indicated they are bluray)
are hybrid discs

You'll see much better quality if you get a Blu-ray player and output with an hdmi cable.
