TV/VCR combo dvd player connection

[IwantmyDTV]

I have a Panasonic tv/vcr combo. TV picture is good and vcr tapes play clearly. But most of the time, if I try to hookup a dvd player to it, the dvds don't play clearly. The audio is fine, but the picture is very dark and streaky; almost like how I remember a scrambled satelite channel appearing.
Any ideas or suggestions?

Take a look at the plug you are using to hookup the DVd player.

I had the same problem and found out that one little pin in the plug was not straight standing.

What kind of plug are you using? Single connector coax or 3 plug RCA?
