i have tried to burn 2 seperate movies on to dvd yesterday. both movies recorded one will only play on power dvd on my computer. when i try to play it in my dvd player it is in black & white, and the screen keeps scrolling. the other movie burned half way and stopped i tried about 8 or nine dvds with no luck. i have used dvd santa to convert and both dvd cloner and intervideo dvd to burn them. is it possible that i have a bad lot of dvds? if not any other suggestions? thank you in advance.
