I'm receiving this error message whenever I try and print my project to DVD.

Project settings are:
Frame size : 720 x 576
Frame rate : 25.00( 25/1 )
Pixel aspect : 1.4222
Field order : Bottom Field First
Rate : 48000Hz
Sample size : 16 Bit
Channel : 2
Rendering format : DVCPRO50 AVI
Over Scan Size : 3 %

I'm guessing it's the DVCPRO50 AVI bit it doesn't like?

I have tried printing to file only and skipping the DVD burn but it still fails to encode.

Any help, greatly appreciated.
