This is kind of a two part question. I'm using hdmi out to watch avi files on my big TV. Some files play great through the baked in "Movies" app. Others don't have sound... The kicker is the baked in Movies app has some sort of override on the hdmi out. Instead of just mirroring the screen like all the other apps do the Movies app actually manages to send a full HD output to the TV (so the movies look great). If I use a different app (QQ player or Mobo) I get sound but when hooked up to HDMI the output is terrible. So... is there a way to upgrade the codecs for the baked in Movies app? Or, is there some sort of override on the hdmi out that I can access to force full HD? I'm rooted... old version of the system still.
