Hi all
this is my first post so hope it helps someone
after buying a new 2" PMP player after being used to my1.8" MP4 model I suddenly discovered that it was a rockchip machine and started to panic when I thought that I couldn't convert my videos
However those very kind people at Uxcell have a programme that works perfectly with my machine
it can be downloaded here
AViConverter 2.0 software
I am now so happy with my player , the 3d sound is amazing and the ability to adjust the sensitivity of the recording microphone is a blessing at rock concerts
I'd highly recommend you taking a look at a rockchip player !!
