What cd medium are you using -- Sony, TDK, Memorex, some cheap Rytek DYE based crap??? What do you mean by eperformance cdr's, is that a brand name...eperformance??? Also I found when burning cd's at lower speed, they somehow become more compatibl with various reading sources. Like car radio's and older cdman and even really old stereo systems. Although till today I have a system which looks likeits from the 80's and is one of the first ever cd players invented which refuses to read any burn at all. It will ONLY read originals. I even tried throwing good name brands like sony and tdk and memorex and even kodak (as low as 1x burns), I think the next thing I am throwing is the system.
Google search an old program called cdridentifier and see what it shows for the dye used. I really wish the author would update this but is no longer working on it. It was a great small nifty tool and still finds till given day most dye names on the cdr's.
That does leave me with a question for the more experienced users here, and the admins, why does burning speed affect compatibility? Its obviosu it does. Any technical reference you guys can point me to?
