I get very good VCR images on my Elite 58" 16X9 RPTV, but it took some work to get them because you're dealing with an analog system. On the other hand, DVD's give you great images with very little work.
I use a high end VCR, a good S-Video cable, and use a separate input on my Elite so I can have custom picture settings dialed in just to optimize things for the VCR.
If you like to enjoy films from many different eras you must have a decent VCR setup because many great films are not yet on DVD ........ or some not on laser disk either.
I try always to buy widescreen VHS movies for my RPTV and I expand them out to nearly fill the screen for a quite passable home theater experience. I often use simulated surround sound to juice up the audio, but DPL II would do VCR sound better.
For instance, try to find Hawaii, Lion of the Desert, Wind and the Lion, and The Martian Chronicles on DVD (or laser disk either).
