Have you got a 3D TV? I'm waiting for (hoping for) my kids to accidentally smash our old TV with a baseball bat or something so that I have an excuse to buy one. And, hopefully by that time, they'll be cheaper.
Regarding the 3D Blu-ray: Indeed. It's a slightly miserable process, and I worked very closely with the author of the SSIF splitter tools to fix bugs that were preventing the right-eye video from being usable in Adobe Premiere. I've now redone a bunch of 3D discs, mostly in black-and-white, then rendered out using the XDCAMHD 50 4:2:2 codec in Premiere. I've found that 4:2:2 makes an enormous difference with this stuff, since all the chroma contrast introduced by the anaglyph-izing is a pathological scenario for 4:2:0, and leads to a lot of nasty-looking edges. I've also discovered that MainConcept won't do 4:2:2, even when you choose that profile. What a PoJ! Thankfully, the MXF->XDCAM presets work very well.
