I am running modified 7/24 & no GE.Using RockPlayer: Kia Soul commercial & all MP4s that I tested, video runs very slowly. This video is supposed to run 1 Min. Audio runs 1 Min. Video runs 1:50. Same with other MP4 videos.Using PDMedia Play Video: Video lags audio by less than 1 second, but too much to be usable.Video quality in all cases seems to be adequate, but A/V sync problem makes it useless!What should I try? BTW Kia Soul commercial is: 4.57MB, 480x270, MP4
