DVD STUDIO PRO - Compiler file error

Hi all,

I am building a very simple DVD in DVDSP. The film (10 mins, DV PAL) is already formatted to MPEG 2 and AC3 audio using the '90 minute best quality' setting in Compressor. No probs at all.

But whilst trying to burn the DVD in DVDSP just as the 'initializing' dialogue box comes up, it immediately stops and another dialogue box comes up that says 'Compiler File Error - formatting unsuccessful'. I've never had this problem before. Does anybody know what this is and how to fix it?

Thanks in advance.

Mat.
