S-VHS vs D-VHS

[Captainclock]

I've never even heard of D-VHS before, I've heard of S-VHS but not D-VHS, and what I know about S-VHS is that its a nice step up from regular VHS as far as picture quality goes and has lots of wonderful special effects that goes with them, most of them of which you may never need but they're there for you just in case. I used to own a nice JVC S-VHS machine a while back and while I wasn't able to fully utilize all of its features because of not having the original remote it did have really nice video playback even on regular VHS tapes (S-VHS tapes were required to fully utilize the potential of any S-VHS machine).
Anyways I would just go with an S-VHS machine since those are more reliable and more well known than the D-VHS machines (which I'm guessing that by the sounds of it D-VHS was a "Digital" version of VHS and was a last ditch effort to save the VHS format when DVD was coming out, so probably why its not as reliable as S-VHS which was only partially Digital).
