For you guys with the factory or aftermarket DVD players installed, have any of you had any luck playing burnt DVDs? I have a Blaupunkt ME1, no progressive scan, installed in my Sequoia and can't get it to play certain burnt DVDs, "- R" I believe. I have had success playing purchased blackmarket DVDs and was wondering what format are they? I know that the common formats are -R, +R, -RW, +RW, but how would you be able to format them to play on factory/aftermarket players? I was planning on getting a DVD burner but want to make sure that the burnt DVDs will work in the car player. Sorry if this seems obvious to most of you but I'm not very up to date with computer technology. Thanks in advance.
