the current 27 series rockchips are good and support alot of formats but they still can not really truly do a no conversion, drop on the player, there will be problems
there are new players coming out from all the big names that are using the new chinachip chip and thsese are a lot more forgiving
ainol v3000HD
onda vx535HD (4.3" 16 million color 800x480)
and many others too with this chip and they are looking good but i will never say no conversion is needed because of the pure fact that vids come in so many different formats and setting that NO player will ever be able to claim drop n play
mp4nation will have the ainol v3000HD very soon and the vx545HD is about as big as the psp, in fact see for yourself a member on mp4nation forums has created a 3d model kit for size comparisons
