When i burn my home dvds sometime it work and sometimes dont on my bose lifestyle 28. I also have cheap Norcent dvd player(it was $40 at wal-mart) Most of Dvds that didnt work on bose system work on my norcent dvd player. Why is that? I think 3/10 dvds dont work on my bose system(but it works well on norcent and computer). Is there like firmware to fix that? Im using Memorex DVD+r 4x disk with Nero6 and cloneDVD
