A good player, but aspect ratios are messed up with mp4 material
on December 21, 2011
The design of this player is good. However, when used on the Kindle Fire to play my own mp4 files of films and shows there is a major problem. The problem is that mp4-encoded films that are in widescreen format are force-fitted to the Fire's screen in a way that messes up the displayed aspect ratio. All the films that I have tried to play were rendered with an aspect ratio that was about 16% too "tall", causing everything to look stretched vertically. For instance, a film with a true aspect ratio (correctly rendered from the same mp4 file as 2.385:1 on my PC and on an iPad) was rendered on the Fire as 2.068:1. Another film that had a true aspect ratio of 2.237:1 was rendered as 1.987:1. I find this "squeezing" of the image to be so annoying that I have given up trying to watch films on the Fire using my own mp4 files. (Amazon-coded films, bought from Amazon, do not suffer from this problem.)
I suspect that the root cause lies within Amazon's code, not in this particular app, since the same problem occurs with the Fire's native video player. However, I make this comment here in the hope that the developer of this app will put pressure on Amazon to either (a) fix the underlying problem, or (b) tell them how to correct for the issue within the video player app.
