Why Does My DVD play in Black and White and Not Color??

The only two reasons I can think of that something would play in black and white are:

(a) you are using an S-video connection and there's a problem with a connector or cable. If the connection is loose or broken, you can see an image but it will be black and white.

(b) viewing a PAL disc on a NTSC TV... I've not tried it but I thought that you can sometimes see the image but that it is black and white. There would be other problems with the image too, though, not just a lack of color.

What make and model of player are you using? What kind of TV? Are you using composite or s-video or component connection? Are you using DVD-Rs or something else (-RW, +R, +RW, dual layer)?

Seriously, I can think of no reason why it would display in color on your computer, but not on your TV.

How is your DVD player connected to your TV? Are you SURE other DVDs play in color?

Did you somehow create a PAL disc instead of NTSC? (Or vice-versa?)
