Hello!
The settings menu software was updated in April of 2020 (as is noted at the top of the tutorial you linked), so if you ordered a Tiny Video Player kit from us or a distributor before then, you probably do not have the settings menu software. In that case, I would advise re-uploading the program:
https://learn.tinycircuits.com/Kits/Tiny-Video-Program/If you ordered a kit after April 2020 from us, you should have the settings menu software. I would advise making sure you hold the top right button evenly when you turn the unit off and then on to access the settings menu.
The remote does not directly work with the Tiny Video Player kit. You would need to change the Tiny Video Player mode off, and the TinyTV mode on using the settings menu to be able to use the remote with the device. The remote only works with the TinyTV program because it is intended that the remote should be used with the TinyTV.
If you still cannot get the settings menu working, or if you wish to use the Tiny Video Player kit with lower volume, you can edit the Arduino program after downloading it from the above linked tutorial.
Best,
