Good evening all,

I have noticed that when i watch a tv show in HD the picture is somewhat
grainy. I have digital cable thru Videotron Montreal using the SA
8000HD. What can cause the picture to be grainy and Is there any way to
cure the grainy picture

What kind of graininess is it? Is it digital compression - like a highly
compressed JPEG?

If it is... Videotron maybe be overcompressing the video feed.

Theres no telling, it could be a number of things, if your cables like mine
its loaded with snow and other crap. I sometimes think they do this
deliberatly so you will get one of their digital boxes, but this is a first,
a grainy HD picture.
Check your connectors, make sure they're tight, and any splitters and line
amps you have are at least 900mhz, so that they pass all of your signal,
you might have to call your cable company. One short term fix you can do is
turn down the sharpness control to zero, all these controls do is amp noise
and add it to your picture with little if any benefit

For digital cable you need 1ghz+ splitters.

They are preferred, but 900 mhz work fine, I have a box full left over after
I replaced them with 1 gigs.

900mhz can be flakey with digital cable and cable modems. They seem to
corrupt the data stream causing breakups or slow downs with cable modems.
Especially if you're splitting runs more than once or have runs longer than
2 feet, you'll definately need 1ghz splitter. But in anycase, since 1ghz
splitters are only a couple of dollars, might as well go with the right
type!
