Hello!
I have this problem - then i start reading CD-Rs (with personal data, single track, no multisession)
at the beginning Imgburn says "Reading Media Catalog Number...", this lasts for about 3 minutes, after that Imgburn starts to read the disk.
Drive - Liteon iHES208 (FW used - 8L09 and latest 8L0C).
maybe it's just a problems with liteon firmware
And question - is it possible to completely disable MCN reading? Or if not, maybe will you add such option in future release?
ps if i check "View media informartion" - it says Media Catalog Number: Unknown
