DVD question
One purchased a box set of DVD's last week, nothing untoward in that, however for some reason they refuse to play in a TV player, neither on my laptop, but on another laptop they played perfectly, this one being 2 years old approx. Why would this be ? Is there some code within said disks (tried several, same result) that only works with a certain level of up-to-datedness in the hardware. I've not experienced this before, except with a corrupted/damaged disks. Said box set is of digitally remastered old material. Any ideas ?
