Thanks. I saw that info; it was what convinced me to buy the software. More detail: I picked a small video mp4 file, told the software to save to Disc/Disc Image with output set to DVD. The progress indicator dialog says "Creating DVD, Phase 1 of 1 0%" and it has for the last hour with no change. When I clicked the button to start, it spun up the DVD drive a little, then stopped it. The program is taking up about half of the available CPU cycles but not indicating any progress.
