Burned my files with this software and trustly removed them from HDD. Well, when i put DVD into my dvd-rom, system did not even recognized anything is in it. So i tried cleaning disk and inserting it into my laptop's drive (driven by Ubuntu 12.04). Same result - no disk detected in the drive. Other disks burned by @cdburnerxp do work correctly in Linux (did not try on windows). That is really sad.
