I used my hp200i to make a good copy of a mpeg file that plays nicely in my home computer but not on my laptop-- have a friend who has basically the same laptop-- same dvd-rom--same manufacturer-- same software and the disk palys fine on his-- mine says theres no info on disk when I know there is--- have PowerDVD and WinDVD and have compared everything from ---aspi"s----codec----atapi----can't figure it out-- winXP has a prompt for files and what programs will play what format--my friends prompt comes up with winDVD &PowerDVD --just like mine does with store bought DVD but not my laptop
