I've been using prodisc 4x but are not having very much luck with them. I've used them successfully before when we had a panasonic burner so I 'assume' they are not compatible with our new burner. Sometimes the burned dvd will play completely without any flaws but then with each subsequent play it starts skipping more and more. Am I right in assuming it is a media/burner incompatiblity issue? If so which media would you recommend for the pioneer dvr-108?
