Ok guys...
Finally this about the chipset was unveiled... i did open my player!... :? .
Happily no seals was put in there... so my warranty is still alive...

This player is based on chipset
Actions ATJ2135 which is so new that all the information is in Chinese.
Nor even Actions semiconductors have information about it.
What i found inside was :
Chipset: Actions ATJ2135 - G51370A
BIOS: GTE ES/T ... whatever
Flash: M... 0728 29F8CCMAA... whatever
FM: Philips TEA5767
In the net there is lots of information about including some screen, information about SRS... but all in Chinese :
