burn in pioneer A06 and don't play movies

[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 successfullyl.

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