Bad Picture
I am using Dish VIP 722 receiver and have been using a 32 inch CRT TV that is a distance (app. 30 feet) from the receiver. I have tried two sets (32 inch Sony NSX 32GT1 and Samsung UN32D4000) and neither picture looked as good as the CRT picture. I am using coax cable because the distance is too long for HDMI cable. Would a signal amplifier improve the reception? I really want to replace the CRT with a flat panel, but I also don't want to keep purchasing and returning sets. I can get the better deal from Amazon than locally, but more hassle to return it. Any suggestions? All help appreciated.

"WHY" did that great Receiver have to be so-improperly Installed at all, please?
No Customer would have ever been "Told" to do that, certainly including by the Original Installing DISH TECH !!

Re: Bad Picture
The key here maybe: "I am using coax cable".
Coax will not transport HD from the 722 box but rather a NTSC 480i version of it (due to the box not the cable), unless you are using the coax solution of some HDMI extender manufacturers, which I think you do not. Coax from an over-the-air antenna will provide an HD signal to the HDTV's ATSC tuner though.
Your CRT, assuming is a HDTV, has given you a pleasant image but tipically cannot resolve the 1920 pixels on a horizontal line with its analog raster, but rather less than 1000 if the TV is good.
The LCD panels you are comparing the CRT with, if 1080p, would give you the 1920 as digital devices but LCD is a different animal that shows artifacts you are not accustomed to see in CRT. If you calibrate the panels they may improve, but other than plasma a CRT replacement with LCD is almost guaranteed that it will give you a stricking picture which is also unpleasant for prolonged viewing if accustomed to CRT.
To be a fair comparison you have to feed them all an HD signal using HDMI or component analog connections (YPbPr, 3 wires), but even those wires will provide some image quality differences, people tipycally think that HDMI would be better but sometimes the opposite is true depending on the equipment you use. If the distance is too long for HDMI (some cables can deal with your 30 feet, Monster has some, although I am not endorsing Monster) consider amps on the HDMI line, or wireless HDMI (although is not cheap).

Re: Bad Picture
I have a 40 foot HDMI running from my cable box to my Panasonic plasma through a Monoprice 5 way switch and it works just fine. The HDMI is a Blue Jeans Cable Series 1--it's about as thick as your index finger.
