MyMPx.org - Help...... Drivers needed

Hello good people.:p
I have a JXD 692 MPX Player(the original name is Microdigit M820) and i believe that it uses sunplus chip set.
I am looking for the drivers for my player.
I have been searching the web for a while but can't find it :confused:
Please Help.By the way I'm using windows xp.
I am looking for the drivers bcoz i cant connect it to my pc.
It is showing unknown device.I checked with other USB cables but it was of no use.
I am thinking of a firmware change.
Will that help?
Is it possible to backup my firmware provided my device is not detected by pc?
I opened the player and found that the chip set is SPMP 3052 D QL 171.
Will the firmware for SPMP 3052 B work on this?
