popcornmix, what you suggested above did the trick! You da man! I had 'Adjust display refresh rate...' enabled, but not 'Sync playback to display'. Appears both are necessary; now movies play very smoothly.

I edited confix.txt in Windows (much easier) as follows:

Code:

avoid_pwm_pll=1
gpu_freq=333
core_freq=500
sdram_freq=500
over_voltage=2
force_turbo=1

I could easily notice the UI nav and performance bump. I think it matches Fire TV speed now, maybe even a lick faster. Also, both Birds 70Mbps and Jellyfish 70Mbps play smoothly. No skipped frames.

Re-tested 2-3mins of a couple of 3D MVC MKV and 2D MKV rips, especially action/movement sequences and no stutters; smooth playback. Need to watch a 3D movie with those high bitrate peaks, like 'The Avengers' final battle sequence, parts of 'The Immortals' and perhaps 'Avatar'.

I'm thinking of pushing it and trying what wrxtasy suggested; wonder if it's safe to...

Code:

arm_freq=1000
core_freq=500
sdram_freq=500
over_voltage=6
