Stretch 4:3 video to 16:9 (wide screen) in WMP 11

I've got a notebook with Windows Vista Home Premium 32-bit. In WMP 11 I'm
unable to find any setting to stretch a 4:3 video to wide screen since my
notebook display is wide screen & I don't like having the black bars on the
side. Anyone know how to do that? I already know of other software
alternatives (so don't list any please) but I want to know about WMP 11 cause
I use it very often to stream videos which are in 4:3 format but my notebook
display is 16:9. Even the external display which I quite often use is 16:9
format. The notebook has a nVIDIA GeForce Go 6150 graphics processor. I know
I can remedy the problem when I sue HP QuickPlay, Media Player Classic & VLC
Media Player but what about WMP 11?

No answers? I encountered such issue also. I have other media player
softwares. They can work well to show my video clips which were recorded in
16:9. However, wmp 11 just can not do it. It always showes in 4:3.

really bad!

I searched in the web. It was said that there was an option in
tools->options->performance->advance-> unselect something like "Allow full
screen control". But it was not true in wmp 11. I didn't try in wmp 9 or 10.
Maybe you can try. I just give up wmp 11 and use the alternative one which
was really powerful for all kinds of video formats!

Good luck!
