I will look for the latest kp49.

Is there a way to play a video with the stock video player using the command line?

The main assumption that was put to test was that OC would save power on high loads. In my phone it does not.

I agree that having data using the DSP would be nice, so we will know how moving the load from the MPU to the DSP impacts power usage.

'dsp' to 'default' is 805 to 600, or about 34% increase in frequency for a 10% power penalty, right?
