• In portrait mode, 720×1280 DPI works on 1080×1920 resolution. http://forum.odroid.com/viewtopic.php?f=137&t=21785

• Audio passthrough for both AC3 and DTS sources where every few seconds there's an audio dropout.

Workaround: Write the codec value to /sys/class/audiodsp/digital_codec sysfs file before executing the media player.

AC3

$ echo 2 > /sys/class/audiodsp/digital_codec

DTS

$ echo 3 > /sys/class/audiodsp/digital_codec
