Using scriptplayer on iphone?

So far Ive been using Handyverse’s local video player on my iphone and load up a video and script through there so I can watch in bed and use the handy. Im able to load these videos and scripts from my NAS. However, there are problems when loading videos over 1gb and some scripts cause a black screen and no video. Im trying to figure out if theres a way to use scriptplayer on my phone. I do have a backup pc in another room. Any ideas?
