Rule #1 - Be Patient - Rule #2 - Don't ask when, if you don't contribute - Rule #3 - You have coding skills - LinuxMCE's small brother is available: http://www.agocontrol.com
When media is playing, you can use the normal keys on the i/r remote to control the media playback and volume. Or press F6 or the 'media' button on the gyro remote, and then move left and right to adjust playback speed, or move up and down to skip through chapters/tracks/channels/songs depending on the type of media. With the left and right movement you have both absolute and relative. Absolute means keep the button held down while you move left and right. This is quite useful with the gyro remote. Press the left button, and if you move your hand all the way to the left you are at the beginning of your media, all the way to the right and you are at the end. Or, tap and release the button, then when you move left and right you are in relative, or jog shuttle mode. Move slowly to the right for slow motion forward, further to the right for 400x forward, back to the left to rewind, and so on.
...ok, so I have linuxmce up and running, but jeez isn't there a lot of configuration and a lot to learn.!!!...
