Hi Sanjay, I will try to help
, but note that it is better to ask just 1 question per post instead of all on a single post
ok, the volume bar shows whenever you change the volume then it hides, if you want volume buttons on the screen then select 'Limo mode' from the special modes page.
There is no 'on' button, I dont know what you mean with this one ?
Music videos will play full screen, but the size of the video on screen is determined by the 'Aspect ratio' the video file, not the player.
You can set the BGM on the background music page, and to play local radio you will have to find the stream url of that radio station. If you show me the stations i will try to help you find the stream url.
To have a random track queue (shuffle), you can set this in the interface options page
