Here's that frame in the '93 DC (Dr Gonzo DVD):

What's interesting, is that the cropping is quite similar here to the Technidisc. Don't know if Gonzo made additional cropping or not for the resize though.

You can see some examples of the infamous split-saber syndrome here: http://originaltrilogy.com/forum/topic.cfm/DVNR-smearing-in-GOUT-not-in-the-master-Or-is-the-1995-release-a-different-master-altogether/post/514542/#TopicPost514542

I'm not entirely sure about this but I think the Faces LD of Empire doesn't have the artifacting seen here: http://originaltrilogy.com/forum/topic.cfm/Whats-missing-from-GOUT/post/463309/#TopicPost463309

If that is the case it could be:

'95 Faces LD = GOUT Star Wars

'93 DC LD = GOUT Empire

Also, the dirt on Ben and the trooper isn't something unique to this master, that's the kind of dirt that was printed in and probably seen on release prints. The speeder pass by shot had plenty of it, and so had the lightsaber scenes in the Falcon to name a few. The yellow and blue stripes is splice tape.
