Hi Mulvey....I see that you have discovered, grasped, and walked into the light regarding this, and all other posts for this 'ahem' brand. So why don't we just convert it to a Region Free player by following the steps below. Please keep in mind that this will not correct all of the problems with this 'ahem' brand, but it will certainly enable greater DVD compatibility. Turn on your player, and using your remote, (i'm assuming that THAT still works) enter the following commands: 1) Menu 2) 1 3) 9 4) Highlight "Region" 5) Enter 6) 0 7) Enter 8) C Please update your post regardless if your results were positive or negative, so we can either continue chipping away, or so that others with similar situations can glean their corrective measures from your post.....good luck my friend
