Same; the more I learned how VCRs worked, the more I recorded in EP or SLP . . . and, I mean, depending on the machine itself, even in EP or SLP, you could still get decent video and audio quality . . . I once had an Emerson TV with a built-in VCR (and DVD player) that was a Hi-Fi, and I have to say, in the beginning, the quality of the recordings, even in EP/SLP, was absolutely amazing: crystal clear picture, and stereo-quality sound!
But yeah, when it comes to EP/SLP, you could easy three feature-length movies, or perhaps about a dozen episodes of a half-hour TV show onto single 6-hour tapes, wherease in SP, the best you can do is one movie, or maybe about four episodes of a half-hour TV show. And I agree, the biggest con with SP was the slower rewind/fast-forward.
But you know, I'm going to be honest, at least with TV recordings and such, there's a certain warmth and sentimentality attached to these tapes for me much in the same way that music lovers have with records. At least with movies, I do enjoy the better and sharper quality of DVD, not to mention the special/bonus features, so in those cases, I'm fine with dumping the old tapes, but when it comes to TV shows, it's nice to hang onto TV recordings on tape, because sometimes episodes of TV shows on DVD might be edited in some way - maybe because of music rights issues, or certain celebrity guest appearances that can't be cleared, or an episode was eventually banned - so home-recorded tapes are the only way of preserving certain aspects of these episodes for posterity.
