I don't think it's anything to do with quality! it's a question of format. Simply put, if your record a DVD on your PC using a [+] format disc, it will not play on your lounge DVD machine if it is only [-] format compatible. Most modern PC DVD writer's will handle both but portable/static DVD players will have to be one or t'other. If you want to record DVD's to replay on your lounge player, you must use the format the player specifies.
