First of all thanks for this great sharing! On subject now, I'm using power kernel with ideal profile and I tried overclocking dsp to 600 before I install the files but got some "media format not supported", "cannot seek" and crashes in both stock and open media player. But I think I found the source of the problem, because after disabling smartreflex for vdd1 I had no problem viewing media files. So I believe that low voltage for high dsp clocks can cause these errors. I tried many values and did a stress test (insane media seeking) with each one, to get my device's max clock for a specific voltage.

I just thought it worthed sharing.
