I just downloaded the latest version and us it with any DVD. At the end of the DVD write process it hits the writing lead out tracks section, and then stays at that stage without ever finsihing. The DVD drive light is off. When I force a stop, it give the standard error message, the writing DVD drive is immobilized (no eject, no play) until I restart. The one DVD i have backed up appears to play OK, but I have not explored it thoroughly.
I have an HP DVD writer in a vanilla Compaq.
