I bought a TV box with DVB tuner (from ********** seller) Armcortex-A9 Neon AML8726-M3 (dual core) Android 4.0.4 seems working perfectly but: a) HD movie playback has breaks, cracks and usually is stalled. I've tried different players apart from the included (such as vlc, mx, BS) b) DVB-T reception is perfect (strong signal) but the sound has delay from image, a tiny one but very annoying Low resolution movies usually play ok. Can anyone help? Is it possible to have hardware problem? (a faulty device?) thank you!
