I have a Sony Vaio with CD/DVD/R/RW and have imported a movie from my new Sony mimiDV camera using Serif MoviePlus which created a .avi file and a .mpg file. I tried to create a movie on VCD using the Serif software and it could not write to the CD. I tried the Microsoft Movie Maker software and ditto. I tried the Serif DVDPlus to create a DVD and it would not write to the DVD, I also tried RealPlayer and it would not create my movie on DVD. Eventually I tried Click-to-DVD and it created a movie on the DVD (but with no sound). My fairly-up-to-date DVD player cannot recognise the DVD from CLick-to-DVD. I can write a data and audio CD and DVD using the drive (sony UA-50 1f). Is there a codec I need or is there some kind of software block so that only (Sony) Click-to-DVD will write a DVD (even without sound)?? Any ideas would be great!! Thanks much.
