Thanks for your reply.
I too can confirm that this works.
I hadn’t noticed though that the spelling of the py had to be changed too.
On my system; the path is C:\Program Files\StreamFab\StreamFab\script
The “C:\Program Files\DVDFab..” path doesn’t exist.
I did create the path you suggested “C:\Program Files\DVDFab\StreamFab\script” and put the file there and nothing happened.
Putting it into “C:\Program Files\StreamFab\StreamFab\script” worked fine though.
Thank you for your help.
