I get wrong disc error when trying to play the DVD's but sometimes the same DVD will work! I don't understand


Hello,
Sounds like the laser eye on your DVD player is dirty and will only read some DVD's some of the time. This happens a lot. I recommend getting a good quality DVD/CD/PC cleaner disk. They will have little bristles on them and work wonders for dirty lenses. Run it through all the way 2 times to get a good cleaning and your DVD player should be back to playing all your movies.
regards, Tony

Input number displayed in corner (V-1, V-2, etc.)


Believe it or not, sometimes things just randomly happen. Remote controls operating using infrared light and coded commands, and sometimes sheer dumb luck results in the TV deciding it's gotten a remote command. This is sometimes more frequent in homes where CFL replacement lamps are in use. The way they work can sometimes cause interference with some remotes, and can confuse the TV as well.

Zenith advanced system 3, can't access video 1 or 2


I just got the TV for free with no remote and had the same problem.  The solution I found is to connect two devices that are feeding live signal (a VCR, DVD player, or game console) to the RCA connector input on the back of TV for Video 1 and Video 2.  I then used the first menu option which I accessed by using the Menu key on the front of the TV and Adjust and Select buttons to scan for channels and detect the band for the reciever to use.  After doing this I changed the setting away from "Fixed" (I forget which setting) and turned the TV on and off.  I then found that by pressing Menu several times I would get new menus.  Before I had done that scan with more devices attached to the other ports I didn't get any other menus.  I also discovered that depending on which devices I had connected I would get a Picture in Picture feature.  It would have its own menu to select its source, but I would lose that feature if I changed the device topography of my setup.
