I did my scaling in VirtualDub paired with AviSynth, personally. But I’m sure there are other ways to do it.
I keep reading about Harmy’s version that used the 06 GOUT upscaled and was wondering what method? I’d like to upsale to the quality of Harmy and then re-sync the audio with one of my laserdiscs which has the 77 stereo track, then output to BD.
