Are about as useful as a chocolate teapot. Heaven knows how many times I have tried to play a blu ray disc and I get an error 'Can't play disc' or similar. Then there's the message about needing a Ext?..All I want to do is play a bloody film. I never had any trouble with the old DVD player but these blu ray are a pain in the backside and I can't seem to get them to work. Anyone else have the same problems with blu ray?
