Just tried the Avia Platinum disk on my Arcam and it locks up the machine! Disk 1 works fine. I have software 1.81 and firmware LT23 (must be Model A drive since it won't update to LT37) Both disks play on my Panasonic portable. Anyone else with Avia Platinum and an Arcam DV27? I'm really starting to regret getting this machine now!
