Thanks for reading this thread, please take the time to respond as this is really doing my head in. Firstly I would like to know when people bought their A1 and what are the first 5 digits of your serial number. I have been lead to believe that this has something to do with the manufacture of the player. However, I am confused as I took delivery of a brand new player only two weeks ago and the Serial number is 21215 - which I believe means 15 December 2002. Secondly, some of you may have seen my previous threads about my A1 freezing during various films. The situation that I am currently in is that I bought a player last October, this then went away to have the new disc transport fitted to resolving the freezing problem, when this came back it was still freezing. Denon then decided to give me another player as they still could not find the problem, however, this also has the same problem. As I have said before, this is simply not acceptable from a player costing £2500!! I have to know whether anyone else is having these same problems or whether it just seems to be me. I am seriously considering asking for me money back or a different player, but I really want the A1, besides this fault it is simply an amazing player. Thanks, Ian.
