Nero Vision PAL conversion

I have made my own video file it’s a avi and it is NTSC form. I live in canada so it works perfect if I burn it using Nero Vision. But Im trying to burning using the PAL format so I can send it to friends in Australia.
When I change the transcoding the Australia [PAL] and try to burn it. It gives me this error “Unable to prepare data for recording: Prepare session failed: Transcoding of videos failed”
It does this right away.

Any sight? Ive tryied to convert my files to PAL from NTSC but that is becoming more of a headache.
