I got my Dx-3220 today and was very upset to find that none of my many backed up dvds, all on Infiniti -R x2 and burnt at x2 speed, will play properly. The picture and sound break up intermitantly. I have tried aroung 6 titles, which I have confirmed again in my old Sony NS330 to be perfect, and they all exhibit the same problem. Any ideas? Unfortunately I bought a large batch of these DVD's and I currently think there may be a compatability problem with them and this player? Can anyone else confirm that Infiniti DVD -r x2 white top disks, burnt at x2 speed work or not with this player? Where can you download the latest firmware, or is that a wast of time? Help!
