I'm glad that that is the default. Maybe I inadvertently changed it on a previous version not thinking I would have any need to burn CD-Rs.

Under the 'Settings->Write' tab, the 'Write Mode' was set to 'DVD', by default I believe, because I never would have had reason to change it. I have only written DVDs up til now. I changed it to 'Auto' and now it writes and verifies the CD-R just fine. Thanks for making me look CAREFULLY at the log.

If I successfully create an ISO file of mp3s and try to write it to a CD-R with ImgBurn 2.4.0.1 or previous version, I get: W 10:34:19 Failed to Write Sectors 0 - 31 - Reason: Illegal Mode For This Track I can write DVD+Rs no problem. Nero has no problems and even the last version of DVD Decrypter can write it no problem. Anyone have any insights? The drive is a PLEXTOR DVDR PX-740A 1.02 (USB). The media is Verbatim 40X (Manufacturer: Prodisc Technology Inc.) though this shouldn't matter.
