I just download the updates when ConvertX says there's one available. The version I am running now, which has caused me all the grief with audio synchronisation, is 2.0.9.119. Prior to this release I have not had any problems. Could be the source material, could be the version. All I know is ConvertX can't handle the source, while other programs can.

I'm a results-driven sort of person, and I bought VSO ConvertX because it gives me excellent results reasonably quickly. The down side of it is that I am spoiled by how easy and reliable it was, so I don't know how to re-process my audio from mp3 to ac3, nor do I really want to know, if I have a tool that can convert my files properly.

NeroVision Express can do it, and has more flexible menu options, but it takes a long time and I don't believe the results are as good. But for me it's a better option than figuring out what programme to use to reconvert audio and jump through a whole bunch of hoops to use a product that I purchased based on its ease of use. If it ceases to be easy to use, it ceases to be what I want.

I hope this audio issue is resolved quickly, so I can go back to using my programme-of-choice.
