Sony portable DVD player will not play movies, screen says "hold on"

If you are using the s-video jack to connect the DVD to the TV, the jack could be loose or the wire could be bad. The s-video cable has 2 signals, the black-and-white (luminance) and the color (chroma). If the chroma signal is not getting through, the picture will be in black and white.

You need to convert avi files to dvd format before burning, otherwise the player won't recognize them. Google "avi to dvd" and you'll find a number of free or pay programs that will do the conversion for you.

i fixed this exactly as previous posted solutions, however a couple of points.
a) recordable CDs work if you don't have a DVD burner.
b) I didn't have a CD burner that would do an "image burn", I downloaded a free copy of "Express Burn" and that worked fine. The disk needs to be "finalised" or "fixated", it should do this automatically, or it may be a tick box selection.
c) I got a "No DWLD 09" when I put the disk into the player. I found this was an incompatibility with the CD-R (Maxwell) I was using. I changed to JVC and it worked fine.

After variety of different tests and findings I have resolved this issue. It appears that the DVD burner was not in good working order and the DVD player was not at fault. Thanks you to all who answered and responded to my problem. Many thanks.

Look on the right side of the unit for a switch that says line select - make sure it's in the "out" setting.
