I found your software after searching the web for something that can handle .3gp files created on a nokia phone and I think it's great - the only problem I have is that when I export something strange happens to the sound (it goes all high-pitched?) no problems with the picture at all. I tried all formats with different settings and got the same result, but I know I could be doing something wrong so I'm asking the experts!
I'm using XP SP2 if that makes any difference
If anyone knows the answer to this I'd be grateful :o)
