steverama,
Forgive me for asking the obvious, but was the audio CD burned in one session? Most car stereos I've seen will not play multi-session CDs, but many home stereos (more recent ones, anyway) will. I have one car stereo and two home CD players (one multi-disc changer and one laser disc player) that will not play all of a multi-session audio CD. They will play ONLY the first session on each multi-session CD. The home theater DVD player and all of the CDs and DVDs built into our computers will play multi-session CDs just fine. None of these players, BTW, has any trouble whatsoever reading either Memorex or any other name brand CD-R media. Heck, most of them will even read CD-RWs that are burned single-session as audio CDs. We burn using either a Toshiba DVD / CD-RW combo drive in my wife's desktop or on an HP USB drive connected to my notebook.
Regards,
Jim
