I have a laptop with LiteOn SOSW-852S dvd-rw with latest firmware (ps08). Usually I burn movies with cheap Vision dvd+r brand and it works fine. But these last few days I've been burning with Ritek dvd-r. The problem with this Ritek dvd-r is that the movie skips heavily on 2 dvd players or won't play at all. I've tried the movie with Pioneer dvd-rw and it's the same. But it plays perfectly on the LiteOn! But few of the Ritek I've burned work on dvd player, though. I don't think it's the media that caused the problem, because it's original RITEK.
Update: now some of my Vision dvd+r don't play on dvd players too! I'm sure it's not the dvd player's fault because I tried the movies with many players/roms. Still, they only play on the LiteOn dvdrw. I've been told that it's a common issue with LiteOn dvdrw. Is it true? Maybe my LiteOn has lost its ability because i used it to burn excessively everyday? What dvdrw should I buy if I want to burn many hours per day?
