I was playing a pre-recorded DVD and it went into something about piracy and copyright at the end.

I didn't seem to be able to stop playing this, which was annoying, so I pushed the "off" button instead.

Now I can't play that DVD. The player makes odd noises while trying to "read" it, then says it's incompatible.

However, I can play the DVD on my laptop and I can play other DVDs on my DVD player.

Any suggestions on how I might get it out of this odd state so that it will play that DVD again?

Long shot, but you could try unplugging the player from the mains overnight and then trying again.

as far as i know there is sections on a dvd which come under
user prohibitions
you press on your remote and cannot halt the disc whatever you do because of the prohibitions.

Some DVD players will try to resume a disk that they recognise from the last played position. If yours does this then I guess it might be causing this problem. Most ones that do this have a limited memory for the number of discs they can remember so if you try to put in 5+ other discs it might forget the one you're trying...

...or you could check it for scratches/fingerprints etc.

Or you could re-author the disc.
