I just purchased and downloaded Dezyred’s “Family Secrets in Cancun” videos using the Play’A app. When I try to play the MP4 videos using media player, they don’t work. The 6K versions play no video and show a duration of multiple hours (which is very incorrect), and the 8K versions result in a error about the file being corrupt.
Does anyone have any insights into whether Play’A or Dezyred is doing something unusual with the MP4 files?
I am able to download videos from VRBangers and VRConk using the Play’A app without issue.
They “encrypt” the videos by inverting all the data in the MP4 files. You can quite easily use an LLM to generate a python script to flip the bits back.

Hey, super non-tech nerd here; how would you run this script on either windows or mac (I can use either if necessary)? Got a few new DZR videos downloaded that I would like to script at some point.
Just adding to this, ran @Islanti 's code through ChatGPT and it claims it cleaned it up a bit. Don’t know if matters much, but here’s the output:

WOW. why did they do something so weak when someone had to have purchased the video anyway? geesh. All the dezyred videos on here went from having the no-free-links tag to them being gone. and more available to people who haven’t paid.
Seems like more damage was done than good by implementing something this weak. I won’t be posting free links anymore though since this is available. Also nice to finally download a video that I purchased that wasn’t on EMP…
Yeah, it makes you wonder. There was another method someone found for getting the decrypted video from Play’a too. Not sure either method works if you haven’t paid though. And I for one am OK with that. Ultimately, someone has to pay or no new content will be produced after all.
That said, if I HAVE paid I expect to be able to use and archive the content however I like. I’m clearly not alone given how people are protesting DRM and restrictions by sharing the content. Something all these porn companies should keep in mind.
Call me a cynic if you’d like but ultimately I don’t think they give a shit what we think about their policies. At the end of the day, if imposing DRM on their content doesn’t really hurt their bottom line in any significant way, they’ll continue to do whatever keeps them profitable. And considering the porn industry still brings in billions of dollars each year in revenue, the studios aren’t clearly hurting THAT MUCH. That said, what it will start doing (at least IMO) is pushing more paying customers into a hybrid situation of paid and pirated content. You can look at what all of the main streaming sites (like Netflix, Hulu, etc) have done to digital content as an example. Piracy is now ramping back up because of boneheaded decisions by billionaires in search of more profit. I think it will only be a matter of time until the porn industry experiences a similar situation all over again.
Thanks a lot for this.
I am getting a syntax error on the first line when I execute the .py file via Mac Terminal. Do I need to amend anything in the code you pasted or should it just work without further edits?
It’s meant to be saved to a file like xor.py. The first line may be tripping up the terminal because it tells the system how to interpret the rest of the file.
Once saved you’ll need to run chmod +x xor.py to tell your Mac it is an eXecutable (program or app) file that can be run as software.
