Test Results: Skipped frames during this highway chase sequence. Video isn't smooth, but little jumpy. Same sequence (via 3D ISO) on my Fire TV and HiMedia noticeably smoother, especially as neither do proper 23.976 (only 24.000).

Make sure "adjust display refresh.." is enabled. With dvdplayer you probably want "sync playback to display" enabled.
Try enabling omxplayer first. See if it works better.

Next edit config.txt. Many ways to do this, but inserting sdcard into windows PC is probably easiest. Try adding:

Code:

avoid_pwm_pll=1
h264_freq_min=333
core_freq=500
sdram_freq=500
over_voltage_min=2
over_voltage=2

If you don't mind setting the "warranty bit" you can be a bit more aggressive with overclock:

Code:

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

Note: overclock is not guaranteed to work, but does for most. It does need a decent power supply.
