powershell script that update titles in real time for wht is currently playing, what will play next and what time the next title will play.

Please understand this script was originally written by someone else on these forums, i have been modifying it over the last three years to add the up next, the time or the up next and to update my website with what is up next... it is sloppy as hell because it is from mind to script nd not formtted at all. I have been using this script or about two years and it works 24/7 requiring a dedicated computer to vmix and this script of at least a core2 3.2 gig processor, nvidia graphics card and 2 gigs ram MINIMUM for running at 420p.

For the last 6 months I ran this at 720p on a lenova thinkpad i7 with 4 gigs ram and an nvidia geforce video built in.

both systems would saturate the ram in about 6.5 days, due to memory bleed in powershell and also in some versions of vmix, so i have it all startup automatically and schedualed an automatic reboot every 7 days.

I run the videos through a vmix input list that has been as long as 13 days of videos with no problems.

I inivite someone or people to modify ts script to use the api list function to pull the next playing data instead of requiring a text file list (aafixed.mu3)

aafixed.mu3 is simply an export of the list input.

I also have found that it is import to have the inputs in this order

input 1 = my channel logo(a gif file)
input 2 = newsHD5.xmal (now playing title)
input 3 = newsHD2.xmal (upnext title with built in clock)
input 4 = List - (The list you will play.)

here is the code...
