Ok, firstly apologies if this has been brought up before but have been searching for a while now and not come across a solution as yet..

I was watching a certain political candidates speech on YouTube yesterday and it got irritating to have to hunt down and select the next part of the video once the 10 minute video cap was reached.
I understand YTs reasons for the cap (probably to reduce the amount of TV/Film posted to their site) and their reluctance to link seperate parts together (for the same reason) but I don't understand why i've not been able to find a FFx addon/script that will be able to link parts together; preferably so that when the first part finishes playing the next appropriate part begins (or secondarily so that it automatically opens all relevant parts in their own tab).

Does anyone know of an FFx addon/GMscript that will do this and if not would it be possible to create one?

Thanks in advance

You mean like this script:

Yes, pretty much just like this (except with Part xx indexing - which I'll mention to this author)
Thank you
