Hi friends, I have the same error message like jonnyboy180.
ImgBurn says: Optimum Power Calibration Failed! - Reason: Power Calibration Area Error
Maybe the error come from a update? ImgBur burns earlier mp3 CD's, avi DVD's, Photo CD/DVD correct - no problems. yesterday after four weeks I would burn a iso file to DVD. My DVD-RW is minimum 8 month old. it is a Optiarc DVD RW AD-7191S with Lightscribe (maybe SonyNEC).
my system: Vista32 home prem, 3 GB RAM, AMD Athlon Dual Core 5000+ (2x2.6 GHz), 500 GB HDD, ImgBurn Version 2.4.2.0, DVD-Rom from Tshiba and DVD-RW from Optiarc
best regards
