It's not that complicated.
Are you running openBh?
Go into the movie list.
Press Menu button, on remote.
Select Settings
Scroll to second page, and change Use Individual Settings, for each directory to NO.
Scroll down and change Stop Service on return to movie list to NO
You can also change the Sort option to Shuffle, if you want random.
Press green button to save, then exit the movie list.
Go to the main menu, select Setup, Select recodings playback & Timeshift, Recordings & Playback.
Check theat behaviour when a movie reaches the end to play next, return to movie list, or desired choice
You might also want to change the display message, before playing next movie to NO.
Save these changes, then test your recordings.
You will soon discover that you have a lot of options, for playback.
As I said I prefer using folders, by pressing the Menu button, when in the Movi list, and selecting the createn directory option.
You will also see various other options, including copy your recording.
