I use different programs depending on the type of disc I'm burning. If I'm burning a non-critical data disc (CD or DVD) I often use Windows' built in tool. For critical data discs (i.e. closed session, closed disc) I often use Nero 8 (soon Nero 9). For DVD Backup I use DVDShrink (which uses Nero's burning core) along with AnyDVD. For authoring video discs in either DVD, HD-DVD, or AVCHD format I use ULead Movie Factory 6. For converting .MKV files to AVCHD discs I use tsmuxer and ImgBurn. Each program/process has its benefits for the particular task at hand. If I HAD to consolidate to one program it would probably be the most recent Nero 9 because of its ability to handle advance-codec video files... though optimizing system performance might require disabling some of the default install settings to minimize background processes.
