In the mean time, while awaiting your answer and for anyone glancing in quickly at this thread
having a general resize issue during different playbacks of TV (video) streams or ordinary video files;
Tools -> Preferences (under Interface Settings [Simple mode] see Interface Type) ->Display Mode
(scroll to) -> "Complete look with information area" (in whatever VLC ver.)
In linux : Tools -> Preferences -> Interface -> Display mode. As advised by
mc2man
I would experiment somewhat with unchecking “Resize interface to video size”,
combine or just choose one of them (unchecking, reverting back to Classic look).
You might need different settings for different occasions.
Always quit and restart after made changes. Don’t know about DVD.
