Hi! Here's the first preview of my Disc burning UDF, it uses the windows built in COM object IMAPI2 for burning.  Features:  Burning data CD & DVD Determine a drives burning capacity Burn ISO files Ejecting/Closing drives Erasing CD-RW / DVD-RW XP users may have to install the KB932716 update to have this working.  Please give me feedback on this since it's the first time I seriously use COM objects.  Enjoy  IMAPI2.au3 (Previous downloads: 862)   IMAPI2_Example.au3
