What should I use to create and burna movie?

I have collected lots of small video files from various sources in lots of different file formats (MPG, WMV, AVI, WM etc) and I want to burn them all to a DVD so I can play them on the household DVD player.

I tried with Nero but got poor quality and the sound was out of sync. :frowning: Then I tried with ConvertXtoDVD and it tool 4 hours to render just 63 files then produced a DVD that the player said was incompatible. :sad:

Any ideas would be appreciated :confused:
