Video shuts off if you exit and how do you display videos

[comet424]

alright so playing with this if have a list of music it shows songs on the right side and when I exit it will still play and you can adjust the audio levels in music

but how do you do the same for Video
there is no audio section while watching a movie or so so you cant change even the subwoofer you gotta exit and goto the music to adjust it

so when you go into the + button bottom right in video and you choose USB4 it has 2 options 2 videos and 11 sources it says 11 sources does nothing and the 2 videos automaiclly plays the first video I wanna list the videos by name or sub folder how do I do this as for the music too I haven't tried folders

I only put 2 mp3s and 2 mp4s on a usb stick in the root... but I cant get the video to play if I goto the main menu like mp3s audi will do it play in the cornor where the radio is
how I fix that and fix so I can see a list of videos by name and be able to adjust the audio levels as the video plays like you can do for audio and radio
