don't play movies burned with pioneer A06

[jose]

I have a pioneer A06 writer and burned various media (optodisc, lead data, varbatiam, ritek), most a 1x speed.

I made backup the movies using software clonedvd, dvddecrypter, copytodvd, anydvd, dvd shrink and play the movies in LG 3520 y Apex 3201 dvd players, successfully

However, in the player of a friend (Daewoo dvd S200) can't play same movies, why?

I checked the DVD players listing on this site and they don't show an "S200" model.
You don't say if the S200 will play other burnt disk's! Some DVD players just won't play burned DVD's no matter if it's -R or +R.
