Black and white

I have found that my discs do not work in playstation 2s and a few new dvd players, they play but only in black and white why is that? is there a way round it? Please help!!! Im using dvddecrypter, dvd2onev1.1.1 and nero to copy my dvds.

Could this be your problem?

Thanks that tells me what it is. I have read somewhere that changing the video_ts.ifo in ifo editor to region free may solve this also i will give it a go and report back
