I'm not sure if this is the best place to post this but I'm relatively new to the Android ecosystem; I've dabbled with phones, tablets, and various other devices like an Ouya but never to a serious level. I recently came into possession of a Galaxy Tab 10.1 that I'd like to use with Plex to stream videos when I work out; I'd previously been doing this with a Wii U and the Plex Web interface to great success. That system had no trouble playing high bitrate 1080p video without transcoding, though it would often lag behind if the video was also 60fps. Since I got the tablet I figured it would be a better solution, it features a bigger and better screen after all... though not by much. Anyway, the device is pretty old and underpowered, and videos using the Plex app are a stuttery mess at native all the way down to 720p. If I set Plex to 480p / 2 megabits they play relatively smoothly, but they look pretty awful. Samsung stopped supporting the tablet at 4.0.4 so I figured I might be able to eek out more performance (or overclock) with something like Cyanogen / what have you. HOWEVER, here's the rub: the Galaxy Tab 10.1 is a South Korean model: SHW-M380W and the ROM support, at least to my "relatively new to the ecoystem self," is woeful. Does anyone have tips on what I can do to get a cleaner / better ROM on the tablet? Or Plex tips? I realize it's really long in the tooth at this point and probably not worth the effort, but it surely must be able to at least do 720p video without choking, right?
