Videos with 4:3 aspect ratio stretched in widescreen. No good!

Just bought a Connect Wireless Stick and make some test. It is good but there is a big problem: in my iPhone and in my IPad all the videos in 4:3 aspect ratio are play stretched in widescreen format. This is very strange because there are a lot of player around where (almost) there is a little switch to tap while the video are playing to change the aspect ratio.

I really think you must fix this problem in a next release of the app or the firmware.
