Unfortunately it has been a waste of time and a PAL-DVD-9 is currently unavailable on the site I've found. From what I have noticed via a torr.-check is that a PAL.iso is available but incomplete. Where can I find the PAL.iso?

Here are the two different iso-sizes:

NTSC: 8.166.532 KB (8.362.528.768 Bytes)
PAL: 8.114.144 KB (8.308.883.456 Bytes)

The NTSC & PAL versions do have different file sizes due to different framerates etc. There is nothing wrong with those reported filesizes
