I cannot see a way to do this - so maybe these are new feature requests? I have just purchased MC17, 17.0.165, mainly for audio playback, but I would like to play video as well. There are two features which appear to be missing in Media Center 17 which are present in XBMC and MS Windows Media Center.
Firstly, in XBMC video settings, I set "Playback > Display 4:3 videos as ==> Wide Zoom". This means that I do not have to manually stretch 4x3 videos every time I play them. I do not want to set the MC17 global video setting to stretch or crop - as that applies to all videos.
Secondly, MS Windows Media Center has a video zoom option called "Dynamically stretch video to maintain aspect ratio in middle of screen". This algorithm is superior to stretch - or crop - as the 4x3 appears normal - apart from slight stretching at the edges.
Can you please tell me how to achieve these options - or please consider these as requests for future enhancement.
