Had the pioneer 5100 for a while now, good results - stuck with the ritek discs and have worked well. However created some discs the other day and i tested them on my pacific (cheapie) DVD player. They wouldn't play on the pacific at all, however the same brand of disc created with encore+PA06 plays fine on the pacific being the same disc and DVD-R. I know the pacific is a cheap player but we thought it would be a good test bed for an average DVD player, and it will play DVD-Rs from other sources, just not the pioneer 5100. Any comments other people's findings?
