I've been sayin this for a long time, but nnnnnnoooooo~. See, told'ya so.

Does PS Now support 5.1 sound (DD or DTS) or is it 2-channel-dolby-surround?

other than eliminating some possible texture stream problems/shortening some load times there is no advantage in playing from hdd vs playing from disc

This is really impressive!

Back when I tried it I had pretty bad Internet compared to now and it worked great. It's an awesome service.

Definitely a reliable service, just a case of whether your internet is. I had a lot of fun playing PS3 games on my Vita this way, but Internet wasn't that stable.

Even if its better i prefer the disc

Hmm, I didn't know it was an issue nor a concern. Since there were no comments or threads made about PS Now, I figured it was fine, but it looks like this confirms my thoughts.

Well, the psnow is shapping up to be a good service.Sure, kits still limited in games, since i dont think it has 100% of the ps3 library, and you need to have a good internet and have a ethernet cable connected to it to have a decent experience, but its getting good.But the physical disc will always be superior.Dosnt require internet, its your property(as in you dont rent it and all)And there wont be any worry about input lag and all(assuming the original game didnt have this problem to begin with).And by now, buying the disc is cheaper than renting it through psnow, because some prices in it are just absurd
