So far we still havn't established which version of BSPlayer we're talking about. Could you check and mention it?
In it's installation folder there should be a folder "skins".
What is inside that folder?
If you've found Options->Preferences you can also find Options -> Skins (or keycombination [Alt]/[S])
(or Options -> Preferences -> Skins). What is shown?
The bar at the top is a special full screen version of the skin you're using.
(In full screen you should also get normal skin by depressing [H] (default key unless redefined in Key Definitions & WinLIRC).)
Repeat is not a playlist function, so you won't be able to set (and see) it there.
Repeat-option cycles through: "Repeat off" > "Repeat one" > "Repeat all" > "Random"
The third option repeats all files of the playlist by starting at the beginning of it when it has played all files.
("Repeat one" simply repeats the current file and "Random" ... well ... plays files at random)
