Wavy lines and no stereo

Are they wavy lines throughout the picture or are they just wavy on the side? Waving picture is usually caused by poor power supply filtering. Wavy lines throughout the picture are caused by interference. Try moving the device away from the computer with an extension USB cable it may be picking up interference from the surrounding electronic devices. It could also be defective.

Move other devices as far as you can from the TV. A motor on the same circuit can cause wavy lines too. Try a different set in the same location to see what happens. If different results, probably a bad filter or capacitor in the TV.

Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

The GTCO ROll-Up is not a high accuracy tablet,it is made for general use by Estimators.

Normal accuracy is somewhere between 15 and 22 mil.

Are there any breaks in the line,this would indicate an open on the grid.

Are you using a Tabletworks driver? Check the options and make sure the correct size tablet is in the driver.

I have same problem but only on analog channels!

Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.

That's because this is a quad. It compresses all 4 video feeds into 1 file. When you play it back, it decompresses the video and shows you each camera. Playback through this unit is the only way to see 1 camera at a time. 
To be able to copy 1 camera shot to a DVD, this is what you need to do: You need to have a TV with Video in and Video out jacks.  Connect the Quad to the TV Video in jack and connect the TV Video out jack to your DVD Video in jack. Playback a single camera shot on the quad to the TV and hit record on your DVD. - The DVD will record whatever is shown on the TV. 

You plasma still under manufacturers warranty. Most electronic devices have one year warranty.
The failure in your TV can only be corrected by repairing it.
I would suggest to call philips and ask them to find you an authorized repair center near you to get your TV fix under their warranty.

it could be any of the things you listed, the coaxial output on the dvr, where it says channels 3-4 out, the cable , or the coaxial input port on your tv. the dvd player is probably hooked up with rca cables (red white and yellow) so the reason you dont have the issue with it is because its on a different port, one solution would be to hook your receiver up to the tv using this kind of cable, this would also get you stereo sound, you would then watch dish network programming on a video input channel,
if you want to narrow the problem down, i would suggest hooking a vcr up with the cable thats connected to 3-4 out, play a tape and see if the issue continues, if not the issue is with the dvr, if so try a different coax cable, if this resolves the issue, the issue was the cable, if not unfortunately the issue is your tv
