It feels wrong that by attempting to play a malformed ((not physically – I mean in terms of the data on it)) disc, it should be possible to crash your DVD player, to the point at which the on/off button does not work, and the only way to get the disc out is to pull the mains lead out the back and put it back in again.
However, I made a discovery this evening.
The mind boggles. Bring back mechanical on/off switches.
