DVD screener copy protection

[buzz2000]

I have obtained 2 DVD screeners (legally) and tried to create images of them so i can watch them on a laptop that has no DVD drive.

Iv been using anydvd/nero to make backups for years but on both these discs (The social network and True grit) i get an "unrecoverable reading error LBA...". iv tried previous versions of any DVD right back to v4 in which case the anydvd tells me the disc has been "incorrectly mastered" and it deactivates. iv also tried, clone DVD, DVD decryptor and using handbrake on a mac which just hung for ages, dvdfab dyecryptor which just copied the 2 second fbi warning message then finishes claiming a successful rip.

Iv been out the loop for a while now, is there some new protection I’m not aware of? or am I just being a moron?

The discs don’t seem to work in computers, there’s a screen where it says accept the terms and conditions " i promise to break the disc after use" and you have to accept to watch the feature but in computers it wont let you select i agree.

I was just wondering is it possible for them to engineer discs which will only work in DVD players? and is it a common practice with screeners?
any info or possible explanation would be much appreciated
Thanks

Hi!

Whether or not you've, as you say, legally obtained the two screeners, I'm sure you know that the studios don't want you to copy them - and, based on what you've described, it appears that they've made good headway toward that goal ;>}

I am aware the disks are watermarked and any leaks stemming from them could easily be traced back to me along with a big lawsuit; I aim to steer well clear of that avenue.

I don’t even wish to copy the disk as that would be a violation i just wish to manipulate its content so it is able to be played on a virtual drive and I can review it at my own leisure, as my work computer has no drive.

It was just the level of protection I was impressed by, if its something the studios have in the pipeline thought it might be of interest.
thanks anyway for your input

You wouldn't be facing this quandary if they were Disney releases (instead of Paramount and SONY), because they'd give/lend you a special DVD player:
