Hi, many thanks for your prompt reply, sorry it's taken me so long to respond. I used the link you provided and installed the latest version of videopad and I cleared the cache as you suggested, but the problem persists.
I've tried all of the mpg files which I've created with EASY CAP from old vhs tapes and whilst I can play the mpg files with windows media player and vcl a soon as I transfer them to video pad I get the same distorted image.
As I said I'm new to this and I've never transferred a file in the way you've suggested but I will try. However, as the mpg files play perfectly. I can't see of what use you can make of them? I can probably send you a screen shot which will show a single distorted frame.
What I can`t understand is why it worked fine for the first couple of files I transferred.
