Thanks for that suggestion!
I tried InfraRecorder - seems like an easy to use GUI, and I used it successfully for some other stuff... will keep it and likely use it!
BUT... sadly it doesn't work with Asian-language mp3's... for me, anyway. I even tried changing the language of the program to Japanese (you can do that as one of the features - but then I couldn't get it to accept my settings, they 'OK' button was greyed out. Hmmm...
Looks like I just copy the tracks to another folder, delete any Asian language characters and just do my burns that way... which I did, and it worked beautifully.
Guess I just need an mp3 player for my car really.
