I have a non-commercial DVD+RW of my students' work while teaching in Jordan. It's obviously a PAL signal. It plays fine on my computer but will not play on US Panasonic DVD burner. I brought home a small PAL DVD player but the picture rolls and is in black and white on my Sony Trinitron. This means, I believe, I need a TV set switchable from NTSC to PAL. I don't think such an animal is manufactured. Am I right?
