I would buy the JVC Super VHS vcr model HR-S7800 for $199.95
from www.crutchfield.com It's a great vcr & at a closeout price, plus Crutchfield is a good company to do business with. The regular discount for this vcr was around $299.
Can I ask you how you have your SVHS hooked up with your Tivo. I just got a JVC SVHS to hook up to my Tivo. I can record to the VCR from Tivo, but no SVHS. I have run out of S-Video inputs on the Tivo. I have no S-Video going from VCR to Tivo, just standard RCA video.
My Tivo S-video out goes to the receiver and the Tivo S-video-in comes from the cable box.
When I bought my JVC it had been a while since I looked at the back of my tivo, then I realized it only has one S-Video out. Depending on the receiver you have you should have VCR out's on it. I own a H/K AVR-310 and two of my Video inputs also have associated video output. These outputs will output whatever the active source is on the receiver.
