Best quality for 3D?

[scszscsass]

Wass up' cheaters:shockkk!:,
I have some concerns,i want to enjoy the best 3D experience and my HD tracker has both the ISO forms and mkv 1080p files.Below are the two files :
x264 / MKV / Blu-ray / 1080p / 3D Version 20 GB file
BD50 / ISO / Blu-ray / 1080p / 3D Version (2010) 50 GB file
Explain or send me a link where i can study about the difference between these two,if any.I just want the best possible 3D experience

enjoy the best 3D experience
Then there's no way around the full ISO.

MKV are most likely SBS, either half or full ones.
Given the fact it's only 20GB compared to the 50GB of the full discs, it's either a half one or badly encoded.

For reference, currently an 3D MKV with the exact same quality as an ISO/BDMV would be bigger (~ 2x) in size than the source.

I am content with DVDrips for now. On 1 mbps its the best quality one can hope to get.

720p mkv best for me!

720p mkv movie with average file size of 2-3 GB have best quality:)

720p mkv Works best for me on a 19" display.

Technically, the iso will of course offer you best quality available because it's the source itself, but I'm not sure what are the ways to handle this format.

1080p is of course the best but also is the largest file sometimes up to 40gb ,now with the fast internet speeds its not a problem for some,.720p is almost as good as 1080p ,at least to my eyes.3d also looks good if your willing to pay 80.00 - 200.00 dollars on 3d glasses.
