I just knew you were going to ask me that. :-)
I honestly don't know I how I did it only that I was able to do it.
I have not burned iTunes Cd's for some time. I only did it after I got my truck in Jan. of 2006. I wanted to make some special Music CD's so I opened a iTunes account back then made 2 full CDR's. I remember I had to do something with the iTunes settings (sorry... I don't remember what I did) but it worked and they sound better than the commercial CD's.
The burner I used is a (external) USB CD/DVD burner that bought in the past year. Maybe that has something to do with it. If I recall the CDR's were just basic Memorex CDR's and the files are MP3's on the CDR's.
What I'm wondering is if I will get the iTunes music player quality on my stereo if I get one of those stereos that lets me plug an iPod into it, and dispense with CDs altogether. Seeing how I'm probably getting a new car within the next 6 months, it might be something to look into.
