I have the demo version of Nero 6 Ultra and I was trying to burn a concert to dvd, and I didn't want 2 seconds of silence on each track, so I for my burning method I chose disc at once instead of track at once but it didn't work, well it burned the cd but it added 2 seconds of silence. I had another burning option and that was disc-at-once/96. Would this have been what I should have used? If not, any ideas why disc at once didn't work? Finally, can someone list some alternative programs? Thank you in advance.
