why is "the social network" only available on dvd, no ppv or vod?

This is the first movie I've noticed you can't get on amazon video on demand or ppv from comcast or any of the other vod on my Google tv(there's a couple I don't remember the names). I did a did a search and the only two places I can find it are for sale not rent, on amazon and VUDU, amazon said they won't release it for rent til February. Does anybody know why this is? Did somebody make a deal with blockbuster exclusively or something? I've never seen this before.

No its never like that, Netflix yes, you hqve to wait 28 days for the new releases but cable ppv, amazon., and VUDU for sure and I'm sure others all come out the same day as BLURAY/dvd.

CINAVIA wouldn't have anything to do with why its released on dvd but not on ppv etc.

first I'm not at all upset or in an upheaval by any means, 2nd I'm sure lots of people know and Im sure il have an answer within A day. Next, I don't even want to see it that bad, my girlfriend wanted to see it and I started looking all over ppv and vod sites and couldn't find it. usually they have the new release the same day as dvd and I thought it was odd and wanted to know if anybody knew the ansr, that is basically why people ask questions, ya know. Why would even ansr a question like that, you could apply the ansr you gave me to every single one of the thousands of threads in here, ""why ask that question," "hmm" "it could be this, of it could be this or it could be that, who knows it could be a lot if things, if you really want to yada yada" I wanted to know because I was curious, thanks for the great wonderful help, I very much appreciate it.
