Pure nostalgia.The way the film looks on laserdisc is what I like to see. I have the dvd too, but every time I watch it I end up feeling a bit disappointed. The outlines of the characters are so thick now. It looks too cartoon-esque for my taste. For some reason the laserdics version looks much more mature.
The text I bolded caught my attention. Just a few days ago I was actually comparing my new Aladdin UK blu-ray to my old Aladdin UK DVD (the 2-disc edition that came out 2004ish), and I couldn't help noticing that on the standard definition DVD the line-art does seem abnormally thick. Also, the DVD has another issue, that being a very annoying case of aliasing - mostly on the lineart and sometimes even on the background art. Since, if I recall correctly, you live in the Netherlands, then I suppose your DVD is a PAL disc and looks the same as mine. The new blu-ray, being high definition. is a definite improvement on the old DVD, and the lines look thinner and finer
. However, the colours are mostly the same, so if they bothered you on the old DVD, they will too on the new blu-ray.
Have you tried tinkering with your TV's contrast/brightness/saturation/etc. settings to get better results on some of your DVDs? It can be surprisingly effective.
Also, you could do what Escapay
said, i.e. buy a video capture card. But I hardly think you would be doing the film justice watching it on an outdated, murky, non-digital transfer from the early 1990s!
