If someone is interested, I found some DVD recording of 1997 SE trilogy I made some years ago, originally broadcasted by Rai 3 (one of the italian national channel) in italian language; the video quality is really low - not thanks to my old DVD recorder... - the aspect ratio is about 2:1 so unusable for any restoration; but maybe someone wants to use the opening crawls and end credits in italian!
I extracted the audio soundtrack with TSMuxer, the resulting files are AC3 2.0 48khz 384kbps. I know the source isn't the best available, but at least there are italian soundtracks available for the 1997 SE - if someone want to add these ones, they are ready to use, just the two ROTJ files need to be joined.
In the near future I'll capture the italian 1997 SE VHS version, HiFi stereo, with both my two good S-VHS video recorder - a Panasonic and a JVC (altought without TBC, I think the hifi audio will play well), then I'll choose the best result; I thought to pass the audio from the VCR to my Sony MiniDisc recorder (because it has a really good A/D converter - 20 bit delta-sigma ADC - that I think is really superior to the simple 16 bit audio card of my PC) then feed its digital out to my PC. Is there something like AviSynth median I could use for audio?
I'm happy I decided to drop DScaler and instead use VDub to capture some laserdiscs - at the end, I captured 1 hour with NO frames dropped - just disable the preview... my video experience is slowly growing!
