Ulead Video Studio 10 - Crashes

[astral]

I am using Ulead Video Studio 10 to create a holiday movie.

It crashes everytime I try to burn a disk.

It does build two files:

1. Video.mpg.mpv

2. Audio.mpg.wav

How can I combine these files to produce and burn a complete dvd?

Thanks

PS I have loaded the SP for the s/w

I ended up downloading the trial version of the Ulead s/w which works for 30 days

and it did the job correctly.

I still do no understand why my copy did not work.
