I have a panasonic dvd-S55 player and for some reason it plays burned dvd's in black and white (usually I use ultraiso to burn iso files and recordnow to burn video_ts files). It will play retial dvd's fine, and the burned dvd's play perfectly on computer, but using the dvd player, they are black&white. The sound plays fine, just no color. I use a dvd+r. If anyone can help me fix this problem, please reply.
