Page 1 of Troubles in regions

I have hacked both of my dvd players, an APEX 600A and my Samsung 709 to be region free. I bought 3 dvd`s from Australia and only 1 plays back ok, the other 2 "The Thing" and "Bladerunner" gets ejected with the message that they are R4 and cannot be played on this dvd player. What am i doing wrong???? HELP!!!!!!

Do both players eject the same films?

Just a thought.

You say "Hacked" and not "chipped". Unfortunately, handset hacks are notoriously fickle and can often refuse to play specific discs. The samsung will play all R2 & R1 discs (RCE aswell), so this is clearly an R4 problem and it`s hard to find info on that region.

yep
also what`s the difference between region-free and multi-play?
Does this have anything to do with PAL, SECAM and the likes?

Yep it does.

Yeah, but what about the APEXAD600A?
