I have a model AD-1500 Apex player. There's 3 different disc settings on it: NTSC, PAL, and Multi. Does this mean I can play NTSC, PAL, and other regional DVDs? If so, I'll have to order some non-region 1 discs over the net that aren't available in the US. I lost my manual to the player, so I can't look up my question in the manual.
