I have used this recorder for 6 months, not very extensively I might add, but have this week been having a problem attempting to play pre-recorded DVDs, both region 2 & 1, all fresh from their cellophane packaging and virgin. The machine is taking an eternity loading a DVD and invariably a message appears saying Incompatible or Unreadable Disc and the disc ejects. According to the manual this message may appear if the disc is dirty or damaged. But as previously mentioned these discs are brand new and I had no problem in them playing after on my old Toshiba DVD player. I have tried playing discs which previously I had no problem with. One or two play but the majority are now unplayable. Has anyone else experienced this problem or have any idea what the fault could be? I would also had I have been experiencing spasmodically a loud whirring sound during playback.
