Good afternoon
As some of you may know I have been having problems with UVS 10 causing my audio and video to go out of synch while rendering MPEG-2 files. For a full description of my problem see here:
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=24812
I decided eventually to do away with UVS and to use Womble MPEG Video Wizard instead, and I thought I was all done with the problem, but then I discovered that I had a handful of files mangled by UVS which have good quality video but out of sync audio and I needed to restore them. So I tried 3 different methods of restoring these files and I am posting my results here in case it saves time and aggravation for anyone else. As Steve says, restoring an out of synch file should be a last resort: the best approach is to try to prevent it happening by finding out what caused it in the first place.
1. The Steve Jones method. Cost: $0 (assuming you already have UVS installed). This is described by Steve here:

Sorry Steve, but despite several tries I just couldn't get your method to work: the output file always looked exactly the same as the input file. Not sure what I was doing wrong.
2. Using pvastrumento (http://www.offeryn.de/pvas_2_1.htm). Cost: $0 (freeware).
I couldn't get this to work either. The program wasn't very intuitive to use and the instructions weren't very clear, so maybe it can be made to work if you fiddle with it, but again my output files appeared to be just as much out of sync as my input files.
3. Using Video Redo Plus MPEG Editor ( http://www.videoredo.com/). Cost: $49.99 USD. This software was intuitive to use, the help files were mostly fairly clear, and the end result was good: out of synch files re-synched perfectly with no loss of video or audio quality that I was able to detect. So despite the significant price tag, I think this is the one to use if you're desperate. Hope this helps someone.
P.S. I don't have any shares in Video Redo.
Comparison of 3 methods of re-synching an out of synch file

I was also impressed with VideoReDo when I tried it. It didn't fix my particular problem, so I didn't buy it. But, it was easy to use and it just seemed like a good, simple, rock-solid, program. ...I don't actually remember if I was trying to fix a sync problem, or if it was something else. 
And, since I've been editing MPEGs with Womble, I haven't had an occasion to try the MPEG GOP fixer.

Darn, I just fixed all my synch errors with Video Redo so I've nothing left to try out on the Womble GOP fixer...
Actually this illustrates a problem which we relatively non-technical users sometimes have, which is that the programmers seem to speak a different language from us. Until you told me, I would not have known that the "MPEG GOP fixer" fixed audio synch problems. If you click on that box you still get cryptic (to me) messages like "Scan GOP time code" which still don't mean a lot to the average user. The good thing about Video Redo is that it leads people like me by the hand and says "this fixes audio synchronization" and gives you simple tools like sliders which you can use intuitively, and for me that is actually worth paying an extra $50 for because of the time it saves.
