Custom URL & MP4 Videos On The Televisions - Solved?

I think I may have finally figured out how to get MP4s to play on the TV's, or at least one way to do it, and thought I'd share it here in case anyone else was having trouble with it.

First the folder and files we're gonna want to edit are in here: drive:/Program files(x86)/Steam/steamapps/common/VeinDemo/Vein/Content/Movies

Preface To Steps: Make sure the option is on in the gameplay settings at the very bottom of the list in-game. As far as I can tell prefixing your file with "vein" is the key. The existing MP4 that plays at the start of my demo video is a Rick Roll with the file being named "veinroll1.mp4", but I demonstrate how these steps work in the attached video with an episode of Scooby Doo Where Are You?.

Step 1: Make a backup folder for the two videos that are already present in game, I.e. Night of The Living Dead, and the Update Video. Then move them to that backup folder, don't copy them, move them.

Step 2: Start Vein, it makes the process easier as the videos can be changed in real time as long as you're not editing the one that's playing, and find a TV. You kinda have to trick the game here, so bear with me. Drop your desired and renamed MP4 into the movies folder. Turn the TV on, and set the input (source) to URL. Put just the name of the video file here. So using our example, all that should be in the URL text box is "veinroll1.mp4" or like in my demonstration "veinscooby1.mp4"

Step 3: Switch the source back to the MP4 file, select use controls and select whichever MP4 you've loaded in, and it should play, if not try again. It can start to play off the URL source; but to use that for each video is a bit more tedious, i.e. typing it in.

Final notes: you don't have to set the URL source over and over again, just the first time, and then any other MP4s you have should appear and play under the file source. Tested with 4 separate MP4s, even after being converted from mov. As well as NSFW content (cause why not). Just make sure they have vein in the file name, and that the original movies are removed, but not deleted. If for some reason it still doesn't work, fenagle with it a few times, once it reads one, it should read them all. So far no known time limit either, as the episode of Scooby Doo is about 5 minutes.
