You can stream some titles from Vudu or the PS3 video store, assuming you have a PS3.
There are 3D TV channels on Comcast (and other companies as well) that broadcast SBS or T/B 3D - but the resolution is half due to the format.
Thanks! I do have a PS3 an the vudu app....what format is the Vudu 3D? Is it as good as Blu Ray?
In my opinion Vudu is about the best when it comes to resolution. They offer 3 resolutions (if you have the download Internet speed) including a 1080P. Price is higher for the better resolution. They also have free Trailers to test your system. And my TV's came with a free credit to Vudu.
Side by side (which is 1/2 vertical resolution). VUDU has good quality but not BD quality.
I think VUDU has quite excellent quality. And the great thing is you can view 2 minute previews. I suggest watching the opening of Meet The Robinsons and see what you think. The seen with the rain looks fantastic!
Also, don't neglect YouTube. There are a lot of outstanding clips and demos there. And be sure to check your cable or satellite provider if you have one. Some good things can be found there too. I watched the entire Rose Parade in 3D from my cable provider's on demand section.
The 3d through cable is definitely of lower quality than 3d blurays. Many of the torrent sites now have 3d movie downloads. There are many in SBS format, however there are some full bluray isos. The isos are huge files though, typically from 20-40 gbs.
Are those the only two formats of 3D that i need to be aware of?
There are two generic types of 3D. Frame packed, and spatial compression. Blu-ray is frame packed. Spatial compression includes side-by-side, top/bottom, checkerboard and Sensio 3D. The the spatial compression formats, most result in 1/2 resolution (either vertical, or horizontal, etc). Sensio 3D format however is supposed to be near blu-ray quality. However Sensio is a patented format so only TVs that license the format (currently only Vizio, plus a LOI with TCL) are able to play Sensio 3D content.
