oy sounds like my setup.
I have the following
(Antenna) - Panasonic DMR-EZ28 - Sharp VCR - Motorola VOOM - TV
(V-R-L cables) Shinco 868 - Sharp VCR - Panasonic DMR-EZ28 - TV
The Motorola VOOM box and the Panasonic DMR-EZ28 are the digital tuners.
I prefer watching over the VOOM box since the Panasonic's frame rate is awfully low. (it looks like 28 frames/second interlaced) And sometimes the Panasonic's video looks stuttered. Recording is fine, I was able to put some clips from it on youtube.
