Cheap HDMI Dongle (rockchip rk2928)

I have a no name hdmi dongle (rk2928) I remember it worked well when I first got it, but then it got some ota updates and now it seems it will only play MKV container formatted files though the DMR render, I managed to hack into the device and get adb access, (found a secret cgi file), and looking at the logcat most files are failing with this message, something about content range, is it possible to force serviio to fix this?

or a less pleasent alternative transcode every non mkv movie file into a mkv format?
