Full WideScreen ?????

HI ,

I am new in Roku developing and tested the channel creation from the examples in the SDK and used the "Simple Video Player" example in zip folder

changed the URL to my live streaming HLS link ( Coming from Wowza server )

and things sort of work fine .. except I am lost in making the video show a REAL full screen ..

Always there is black area in left and right sides of the screen ..

and donot know if it is m3u8 file format ( tried to create a smil file with data with no use )

so can you guide me a little in here ?? ( with full example please 🙂 )
