more video info in osd

[reven]

i would like the option (in the skin) to display more information about the video file on the onscreen display. things like
- frame rate
- frame size
- aspect ratio
- video codec
- audio codec
- how many audio channels
- audio khz
- audio bitrate


also option to switch between audio tracks (divx 6 allows you to do this via the taskbar icon when playing back .avi files thru gbpvr now, but it would be nice if you could do this directly from gbpvr).
