Sorry for the late response but thanks for having a go at this. Unfortunately i don't have any coding knowledge as it would be great to help out with this project and share the workload and much kuddos to you for volunteering .
I haven't had a change to check the fix yet but will go over it tomorrow and report back.
Just to let you know it is much better now at picking up the trailers. Performed a clean reinstall and update and it was able to pick up many of the trailers that it couldn't before so many thanks.
I noticed on the IMBD website that many of the movies over 3 or 4 years old no longer have trailers available (i am pretty sure they used to) so i guess we are stuck with what ever they choose to list in the future.
Thanks again for your hep Offbyone
