Hi everybody,

I have this strange issue. I had some NTSC footage of my own and made two DVDs on Toast 9. I burned DVD 1 ok, but by mistake I burned DVD 2 as a PAL DVD. Both are region free DVDs.

I decided to check them out before sending them. On my computer they both play fine (15" macbook pro, Intel core 2 duo 2.53Ghz, OSX 10.5.8 on DVD player 5.1.1 - Region set at 1).

I tried them on an iMac and DVD 1 (NTSC) plays fine, but DVD 2 (PAL) only plays the audio ok and shows a green screen. (21" iMac, 3.06Ghz Intel Core 2 Duo, OSX 10.6.2 on DVD player 5.2 - Region set at 4 )

Any of you Mac gurus have any idea what could be the cause?

Thanks in advance, cheers!
