JVC HRS3911U 4-Head S-VHS VCR, Silver
flawed product
I bought the 3911 because of the s-video input and output. The unit in theory has great features, but in practice it was disappointing. Most notably, the color switched periodically to b/w and sometimes the image was lost altogether. This could be remedied by a gentle bang on the side, although that was not listed as an option in the manual:0! I returned the unit thinking I had gotten a bad unit but the replacement was just the same. So I am returning this one and looking for a different model.
