The burning is very stable and takes very short time. What I like most is that it shows you how much space will be left after burning, this saves me much trouble when the DVD capacity can't afford the large file.
The big plus for me is that Aiseesoft Total Video Converter converts to m4v format which is typically used by iTunes and Apple TV. My Apple TV has a 160gb disk which makes it convenient to view stuff on my big screen TV without having to stream on my somewhat erratic home wifi. I converted a 75 minute video in about 7 or 8 minutes.
