Never even tried too , be aware that on some (supposedly low-quality) drives the "extra effort" for reaching the "increased" area on the CD may result in mis-alignments/breakage of the lens supporting/moving parts, and some (supposedly older) drives simply cannot "reach" that area. Rule of the thumb is: until you stay around 700÷750 Mb use CD's, if you need more, use DVD's. jaclaz Yeah...but in my car I have a cd-mp3 player...not a dvd-mp3 player....
