I still haven’t figured out what’s going on with Nero + Plextor 716A.
It usually works OK, but often just locks on ‘burning leadin.’ The
buffer never fills. No clues in event viewer. No way to exit from Nero.
Other apps start to lock up (including ‘my computer’).

Inevitably have to hit the reset button.

1: Has anyone else seen this?

2: Are there alternative programs for burning VIDEO_TS-type DVDs?
At least I could see if it’s Nero or the burner.
