Hi to all.

I got a 8GB 2.8" TFT Touch Screen MP4 player with a rockchip i think, version 00.00.0003 2008-09-09. My problem is that the sound and the video have a bad synchronization. audio is late and a litlle distorted. i tried viDrop and nothing. I have allready tried a lot of solutions that exist in the forum and nothing.

Can anybody help me ?
the player is the same as it: 8GB 2.8" TFT Touch Screen MP3/MP4/MP5 Personal Multimedia Player

P.S. - Sorry my bad english

Dear Sppeeedy,

viDrop is a GUI-frontend for the program MEncoder. This program could be found on www.mplayerhq.hu - including a description of many parameters. To get Sound & Picture in Sync you should experimental with the parameter -Delay=(milliseconds from 0 untill 999) as "Extra Parameters for MEncoder" in viDrop. viDrop offers a PreWatch function to see the result before converting. It could be a long way of Trail & Error to find the right value !

Distorted Sound ? Sorry, i didn't know how to solve this second problem.
