How to Switch Between Multiple Video Aspect Ratios in Album Player

On your HTC Touch Diamond, Touch Pro (or variants) and Touch HD, as well as on devices featuring HTC's Album Player, several supported videos (like 3GP, WMV, MP4) play back through this particular HTC Album Player. Playing back files this way, you’d notice that the video played back fills the screen, but is missing some parts of the movie.

Tap the video and the HTC Album Player controls pop up, with the time and progress display and various buttons: Previous, Play/Pause, Stop and the Aspect ratio button on the far right. Tapping on this particular button will cycle through three video playback modes: zoom to fill (default, which will zoom in to the video height and fill the entire screen), stretch to fit (which will stretch the entire video - distorting it - so it fills up the whole screen) and normal (which plays it back maintaining the aspect ratio, so you’ll probably notice the top and bottom black bars besides the full video). You might not see any changes though if your video’s aspect rate is the same as your device’s display (aka 1.33 or 4:3 for VGA and QVGA and 1.66 or 16:10 for WQVGA and WVGA).
