Hi , for a long time i have had serious quality issues with movie playback on my nook tablet.
I tried a lot of different media player apps to play my downloaded movies and all of them pretty much sucked.
The Issue was these apps i tried used a software video decoder. I finally found a media player that uses the native hardware decoder in the tablet and now my video is smooth beautiful. I found the mx player app and at first it had the same issues as the other apps I have used, but I found a setting to use the hardware decoder and bingo I had great video. I am posting this because I struggled a long time to get video to play nice on my nook and thought the info might help other folks.
