Not stable for my device yet, did a little testing with default dsp and a modified dsp profile. I find that SR is not stable for stock mpu clocks above 600hz, voltage seems to be too low for stability even at default DSP clock(430).
Tried doing a dirty trick to achieve stability by using dsp boost @ 250,
Still not very stable when the the DSP is loaded with 720p video, it results in a definite reboot after a few minutes of playback.
