Thatâ€™s my point I have upgraded to 188.8.131.52 and 184.108.40.206 and thatâ€™s when I had the problem. It actually happened with your last upgrade a month or so ago (220.127.116.11 I think) so I waited a month to see if a new version would make any difference, alas no!
I was using version 18.104.22.168 & 30114 with no problems. As I said I can copy a DVD on a mates PC using any version of NERO and it plays on my Sony fine, I have tried different media (+R, -R various brands) and still the same issue.
I have tried uninstalling to go back to the old version (using clean tool pack to ensure registry etc.. is clean) but even now on the old version I still have the same problem.
Any help much appreciated.
