WMP 11,FFD Show (Full Screen when playing DVD)

Hey!

I am new on the forum,greetings to all!

I am using wmp 11 (vista home premium),downloaded latest ffd show,in order to have subtitles(.srt),while watching .avi files as well as full screen(over entire monitor).My problem is that no aspect ratio correction,and resize on ffd show doesent affect screen when i play dvd movies,only .avi
Dont know which options should i turn on,or turn off in ffd show,in order to have full screen (resized,over entire monitor) while playing dvd movies?
Can somebody help me?

p.s i had problems with codec packs,dont sugest me that i download k-lite,or something,i prefer ffdshow,and only one player,wmp11.Less is Better!

Please!

Cheers!
