Archos media player + codec for HD videos
for others use BS player
MX player Sucks big time
Dice player has a similar 4x volume boost as archos but it allows swiping to go forward and back which archos does not have. Archos also does not allow to change the aspect ratio. You can't watch anything in 4:3 with it. I would say dice is better than archos which seems new and needs to catch up.well i tried playing FHD movies in MX player, the sound was too low and the frame rate was really choppy
so i dumped it and got archos player which plays everything quite smoothly
