NeroVision is good and pretty simple to use. DVD-Lab can make more professional looking dvd's, but is pretty hard to use without taking a deep look. Also im not sure if DVD-Lab can export avi files and such to format which dvd understands, but theres always TMPGEnc program for that. NeroVision in the otherhand has exporting function thought it cannot (atleast i didnt manage to) queue a group of videos to export. You have to export them one at time. Kinda wierd... oO
Presuming you want to make DVD video discs, get nerovision express software, not nero burner, from www.nero.com
Its in package 2, if i remember correctly. Its quite simple to use, but if you need tutorial, i can write a quick one.
