Major blurriness with new HDTV and 4100 receiver

Long Post:

I used to use an old crt tv with a 4100 receiver and it was fine. I got a new hdtv and now when ever there is movement, I get a lot of blurriness in the area with motion. I find the picture quality for SD channels on this tv is quite acceptable when the image has little motion.

but for example if I am in the channel guide, and I press up, the text in the highlited block looks like it bounces up and down for about a 1/4 of a second like it's trying to come back into focus.

This never happened with the CRT and when I tried the new tv out on the HD receiver, it worked perfectly. I moved the 4100 receiver 6 feet away from the hdtv thinking maybe it was causing interference but that didn't help. I tried all sorts of different cable running from the receiver to the tv too.

Does the receiver just not have the power for a big screen tv? This tv has a 5ms response time, could it be image tearing? Signal strength is at 84% btw. Is the cable in my house just not good enough?


Also,

I have a double pronged satellite, it's going to a dual tv receiver that has 1 HD and 1 SD output, and also to two 4100 receivers (one of which is mine). How many HDTV receivers can it handle? Would the satellite be able to handle having a second HDTV receiver in the system? I'd be getting rid of my 4100 receiver btw.

If it was able to handle another hdtv, would the fact that my tv is on the opposite end of the house as the satellite matter. I imagine I would need to run a new cord across the house to the satellite to be able to handle the signal, correct? If the cable that I have now is unable to handle an SD signal then I am pretty sure I will have to replace it. It's a drop down ceiling so, it's easy to string new cable.

what kind of cable should I get (would probably have to go 70 - 80 feet to get to the satellite)
 
If your 4100 is next to your TV and your 4100 is wired with a dual satellite connection, which sounds like it is, you should be able to just connect the current cable running into your 4100 into a new single tuner HD box. From your HD box you'll have to run an HDMI, DVI or component cable to your HDTV.
 
How are you connecting the 4100 to the TV.?

Best possible image is via "S Video" cable, next best is Composite (Red Yellow White), the final and lowest quality is from Coax.

If you using Coax it is possiblt that there is another of Air channel on Channel #3, go into the 4100 menu and change it to Channel #4, tune TV to #4 and see if that improves.

As for the Switch's, if there are 4 inputs and 4 outputs then you have an SW44, this will feed 4 individual tuners that can all be HD or SD.
 
In that case I would tend to think the 4100 is defective although you say it was fine on the old TV.

I run a 5200 to a 50" Plasma, via Composite and it looks just fine, so it can be done.

Can you try another receiver hooked up to the TV.?
 
I have the same problem with a 3100 on my LCD that replaced a CRT that blew up. I noticed a big improvement with S-video over composite, but still there. I just figured it was the cheap LCD I bought, so it doesn't really bother me. Its the same problem with everything I tried except the DVD player with component.
 
the other 4100 receive did the exact same thing as mine. I am 99% sure it's the wiring. They are using the internal wiriing of the house for the 4100s, and separate wiring that they installed for the dual tuner receiver that goes straight from the satellite and then more separate wiring they installed for the receiver to the televisions.

When my LCD was on the dual channel receiver (as in I moved the LCD to the receiver, not the receiver to the LCD), it worked perfectly.

What kind of cable should I get to string from my room over to the satellite for when the guy comes to do the install for the high def receiver?

also thanks for all the help so far

edit:

I should note that if I go into the MENU setting of the 4100, there is no out of focus blur at all, but if I go into the channel guide where it has to retrieve information, there is the blur
 
100% signal, and 50% signal will give you EXACTLY the same quality image. It is all or nothing, not like the old analogue cable snowy picture....
