The best dvd and .vts file conversion software available.
I use both the dvd ripper an the video converter. I have used several other similar products and the WINX ones are much better than their competitors. In particular, the synchronization of the audio and video is ALWAYS perfect. I have gone back and re-converted my video library using WINX. Recently I upgraded to a new version of Windows and my external DVD drive stopped working. Having read the WINX articles on the website concerning this issue, I was able to get the drive working again.
