rerun119 Also sometimes the videos would end at 98% finished when downloading with chrome. I also tried to download them with FDM and they stopped at 98% and I can't get them to complete the last 2%.
I think that could be a big problem, but most likely you have some other issues as well.
From what you posted, I'm not sure you understand file extensions. Everything after the last "." is the file's extension. Every video I've ever downloaded from SLR is in the format "filename.mp4" That is, they have an "mp4" extension. So, making MKX200 the extension is probably not helpful, if that's what you're doing.
If the player is not seeing the video, then you probably don't have the correct file extension.
So, to clarify: The videos should be named either "video_name.mp4" OR "video_nameMKX200.mp4"
The funscript file should be named "video_name.funscript" OR "video_nameMKX200.mp4"
Whether you use MKX200 depends on whether it is a 200 degree video.
