What is the difference between 3D and 3D
I purchased Journey to the Center of the Earth 3D on Blu-Ray
there was nothing that indicated to me that it was the type of 3D that has the Red / Blue glasses and Not the type for active shutter 3D glasses
What should one look for when buying 3D movies for active shutter glasses

When DL-ing them I look for 3D-SBS
but then I am finding that some of them are questionable 2D to 3D conversions
is there a website where you can see a list of movies that are actually available in the genuine 3D-SBS format (or Under / Over format) where those that are questionable 3D conversions will obviously not be listed
so those torrents listed as 3D-SBS in KAT search results can be avoided
Yeah Yeah its easy to tell if you read the comments left by those who already DL-ed it
but many have No comments
Thanks

The 3D for red/blue glasses is called analglyph and the type you want is SBS(side by side)or Top and Bottom or Line interlaced Stereoscopic 3D...
so avoid analglyph and look for stereoscopic

on here theres a list of all the 3d films that were originally filmed in 3D

Note: films listed as "Filmed in 2D" or "Rendered in 2D" in the Camera System column were converted to 3D during post-production
