I've just experienced a BSOD (Blue Screen of Death) while trying to burn a compilation using InfraRecorder 0.44.1_Rev_3 (more precisely, after InfraRecorder launched mkisofs).
I don't remember I ever had a BSOD on my system. Another DVD burning software installed on the portable drive works just fine.
After that, just for curiosity, I've installed the same version of InfraRecorder_Portable onto the host system (instead of the portable drive). Launched from there, however, the BSOD did not occur.
