i have stated already that the original video file for ANH:R no longer exists and that a mkv version would be pointless as it wouldn't be any better quality than someone could produce by using the DVD-9 as a source.

Fair play, must have missed you saying that somewhere else. I'll keep trying to hunt down the PAL DVD9 so I can make the best quality x264 encode of ANH:R as possible.

Also (aimed towards the other comments about MKV), an MKV is a video container, like an AVI. It doesn't dictate the actually encoded format of the video, but the standard in the HD Rip scene is for the video to be compressed to x264 when in an MKV container, but it can contain any MPEG4 video file like DivX, XviD, H264 etc.
