The sample DVD was encoded weirdly, it played ok on WinDVD but the anamorphic bit wasn't set right so everything looked stretched, when I played it through my hardware DVD decoder the video stuttered, so I put SmartRipper on it and extracted the two audio tracks + the video, the stuttering on the tv out of my hardware DVD decoder appears to be because of the weird DVD encode, in the filename of the m2v it says "([0xE0]_Video_NTSC_720x480)" even though it's encoded to PAL format.
I re-authored the 3 files into a new anamorphic test DVD and it played fine on my hardware DVD player and WinDVD.
The audio has been time compressed as with the PAL VHS Moth3r used but the dynamic range has been compressed, I loaded up the extracted PCM into CoolEdit to compare with my definitive collection audio and the explosions just don't have that 'punch' of DC LD audio, most notably during the opening laserblast shots and when the stormtroopers blow the door open.
