Help downloading a "free" but DRM-infected movie

[IFindGarbage]

The film "Martin and Lewis" (2002) is a biopic about the comedy duo. There's no DVD or Blu-Ray or even VHS for this movie. There's no way to buy it: it's only for "free" but DRM-infected so that one day it will disappear forever if no one saves it. I'd appreciate help saving this film from being lost forever.

There is a horrible 360p version on YouTube but Tubi has it in 720p and Roku has it in 1080p. I'd of course much prefer to preserve it in HD.

I know the Roku file is https://vod-playlist.sr.roku.com/1.mpd?origin=https%3A%2F%2Fvod.delivery.roku.com%2F13...2f%2Findex.mpd

But when I try to decrypt with N_m3u8DL-RE and mp4decrypt, it comes out still scrambled. I must be doing something wrong, possibly because of an incorrect key. Would appreciate any help to save this film! I'd buy it if I could!

Thank you so much. That worked great.

I'd like to know if this is a process I could duplicate on my own or if I'd just need to keep coming back to this forum for help?
