Since our tablets dont support vob, mkv, and mpg formats, I was wondering if anyone had some tricks to playing these formats. I have tried Moboplayer, ArcMedia, Rockplayer, and finally payed for Buzzplayer. ArcMedia plays nothing at all... keeps returning me to the home screen of the tablet. Moboplayer plays vob well, but you cant skip forward/backwards. I havent tried mpg, but mkvs have serious audio and video syncing problems. Rockplayer didnt seem to work with me well at all. I dont remember the details. Buzzplayer plays vobs well and allowing skipping around, but mpg and mkv files have audio/video syncing problems. Most of my videos are in either mkv or vob format. Mostly, I like to copy the video_ts folder from dvds to my external hdd. It prevents me from having to waste time with conversions. Does anyone have any other player recommendations or any other ways to play these formats? (like maybe something not in the Market?) Or maybe have a hack or something? (Acer already told me that they have no plans to support additional video formats... which sucks horribly).
