LD image quality is roughly comparable to standard 16mm film, VHS is roughly comparable to 8mm film. There are no home video formats comparable to 35mm or 70mm film.
The pulse-FM data structure on an LD (unlike ordinary VHS/Beta), is defined to hold all the information present in the composite video signal. Depending on source material and the transfer to disc, LD is above live TV broadcast quality: For NTSC, this is 425 TVL (luminance lines horizontally for 3/4 of the screen width) and about 482 scan lines, compared to 330x482 for broadcast. For PAL, the numbers are 450x560 and 400x560, respectively.
Compare this to 240x482 for good VHS (recorded, pre-recorded is probably less). Only recently have Super-VHS approached LD capability, and ED-Beta has gone even further with its resolution of 525x482. Of course, pre-recorded material is not widely available in these VCR formats. Even using S-VHS/ED-Beta to tape off-air still only reaches the 330x482 of the broadcast signal (400x560 in PAL countries).
Compared to LD, all consumer tape formats also fall short in time-base stability, chroma resolution, video noise and audio fidelity.
Although the video signal-to-noise ratio (s/n) appears to be about the same for LD and VCR hardware, it is probably not the same for mass-produced pre-recorded material. The LD process (casting or stamping) does not degrade the signal from master to copy. The tape process, magnetic contact printing, does.
All LD players have time-base-correction; mechanical, optical, analog electronic or digital. TBC eliminates the horizontal line jitter and color errors common on tape.

So you really think a tune-up will help?
Word to the soild hard facts.........
VHS sucks.
