Visteon,
that didn't work! but it did give me a bit more insight into the workings of MP so I thank you for that!
I even backed up my currect installation and started from scratch...same problem...so I took the decision to reformat over the top of the data ('bout 200Gb worth of DVD's!). When that eventually finished I copied a film across from the old drive and it played no problem!
Think the problem was that the data I'd copied to it was the same data I'd copied to the bricked drive and then copied off again before replacing,,,must have got corrupted somehow. Now all I've got to do is repopulate with the contents of about 50 DVDs ! (should keep me off the streets for a while)
