LD Player -> VCR -> TIVO HD

[shower_...@lycos.com]

I've got my LD player composite output going to VCR composite input
and VCR RF output going to TIVO HD RF cable input. VCR is set to
output on channel 4 and I rescanned TIVO channels to pick up the VCR
signal while a tape was playing. The TIVO resolution is set to 1080i
fixed. Will this upscale my laserdisc picture to 1080i?

Sounds to me that "LD to VCR to RF" would be a reduction in quality at
each step.

Not sure if your TIVO would upscale whatever it gets in to 1080i (TIVO
wizards please help here). Even if it does, it can't make a silk purse
(HD) out of a sow's ear (RF).

Seconded. The only signal change I would want in between an LDP and a
recording device these days is from composite to HDMI, via a quality
video scaler. Even if the TIVO does upscale the RF input, you would
likely end up with an image that looks worse than your original, only at
1080i. Imagine snapping a high-quality JPEG photo, then re-saving that
JPEG at 50% quality, then having it upscaled to 150%, then re-saving
again as a TIFF. You will get the lowered JPEG quality at the increased
size of a TIFF, and it will look worse since you upscaled from a lossy
source.

By modulating the composite signal to RF via the VCR you reduced the
resolution of the LD to about 200 lines. Very bad idea. Connect the LD
direct to the composite in of the Tivo. As for upscaling to 1080i, don't
expect a dramatic increase in picture quality.

OK, I never knew the resolution would be reduced if I'm just using the
VCR to pass the signal through. I will try some A/B comparisons
between the A/V input on my TV and the HDMI input from tivo. I've got
a 50" Vizio 1080P plasma TV. I will connect the laserdsic player to
both inputs and switch back and forth while a laserdisc is playing.
Unfortunately TIVO HD only has RF input or cable card.

It's a bad idea but the resolution is NOT reduced to 200 lines. That's
the low end of a poorly performing VCR playing back an EP tape, not a
passthrough signal.

The best picture you are going to get from your LD player is to plug it
directly into your Plasma TV. Don't forget, your TV also upconverts to
1080P/I so there is no reason to pass the signal through your HD TiVo.

Also, keep in mind that the signal recorded on an LD is a composite
(yellow cable if you are in the US) signal. That will usually give you
an even better picture than the S-Video or component outputs. It just
depends on whether your TV or LD player has the better comb filter.

This only applies if the player has pure/direct composite, which AFAIK
is mostly limited to Elite players and high-end Japanese players.
Without it, the composite output is just a recombined Y/C signal after
the composite signal has passed through the player's internal Y/C
filter.
