Hi! I have problem with ZiiO 10 - no sound in most of HD movies I try (.mkv and .avi). I check different video players and problem occurs in ZiiVideo and RockPlayer in Hardware mode. When I try yxplayer or RockPlayer in Software mode sound is working but playback is choppy (RockPlayer shows only 10~15FPS with 720p mkv movie). Does ZiiO really doesn't support AC3 sound while using hardware video acceleration (I really don't belive in that as it is major drawback and I didn't notice it in any review/thread/movie) or I'm doing something wrong?
