I know you can find a laserdisc rip on Rutracker.
I found two there.
Search: lion king ldrip (which is an xvid avi)
lion king laser (which is a laserdisc transfer to dvd5)
There’s also an MKV which appears to be identical quality to the DVD5 version and, unlike the DVD5, is anamorphic. I’d take that over the xvid avi.
