I've noticed that several of the DVD copies that I've done are having a large black border displayed - but only on the Xbox 360 client app. The DVD's are all originals but older films (Commando, Mad Max, Aliens Special Edition) - whereas more recent widescreen DVDs (Kill Bill vol 1 and vol 2) are also widescreen but come out perfectly.
The same MP4 video files come out perfectly (full widescreen) when played on my Android phone, Android tablet, Chromecast - v2 and Roku 2.
Could the devs please fix this as it's getting quite annoying!! (also does the same problem happen on the Xbox One version as well?).
