Ancient-Red-Dragon: And a lot of times, modern OSes have disabled that DRM from working and thus make the physical media which contains that DRM useless and non-functional.
Plus, disc-based movies often only work in certain regions and/or on certain devices that happen to be compatible with that exact version type of the disc.
And even if physical media has zero DRM in it, then it still doesn't last forever anyway. Eventually, the data on it will decay simply through natural processes, and the physical media which used to hold that data will therefore have become totally useless.
The Moment of Silence was like this because the UK publishers, Digital Jesters, stuck starforce in the game meaning you needed to find US files to get it working.
Also they were closed down a year later. Were they unlucky or just a bunch of shitheads?
Despite a well publicised investment,[1] on 22 December 2005 a winding-up order was made against the company in the Birmingham District Registry of the UK High Court on the petition of Kaoscontrol Limited.[2][3] This followed a period where the company was accused of withholding payments to various developers[4] they had worked with, resulting in some developers terminating contracts with the publisher.[5]
https://en.wikipedia.org/wiki/Digital_Jesters13ison: This is certainly an example of the doomsday scenario a lot of us DRM Free fans fear, where digital content can be removed. But there is also the discussion, as it is here, of whether any media is truly permanent anyway. It's tough to see where the smart money would be further down the road.
Then instead of asking how long would a disc last it becomes a question of how good is error control when copying and how do you decide what's worth copying in the first place.
