Increase your chances of writing & reading accurately by burning at a slower speed (e.g. Nero Drivespeed) and by cleaning the lenses.
My 1991 Meridian CD transport won't read 80 minute CDs, ever, at all - but that's an age related issue. It has no problem with 74 minute CD-Rs, but won't read CD-RWs. My car CD players read 80 minute CD-Rs - I don't think I've tried a CD-RW in them.
I have found CD / DVD burners to be of variable quality, so all of my desktops were built with 2, from different manufacturers, to increase the chances of writing and reading correctly.
