Hi Antti,

thanks for that information.
The only real new information for me is the 16.000MHz xtal value.

Sad to know that the other chips are hidden.
I assigned more i2c addresses to functions, but not yet all (no idea if 
more addresses are real, or bad interpretations of snooped data).

I now try to check what already works:
- This is video via composite input.
- Next is to try video via analog input - see I see if the tuner in 
general works in this device.

In parallel I try to capture usb in different setups.
1. kvm+tcpdump (using usbmon)
2. usbsnoop on windows vista

Only setup 1 does provide a real list of usb packets.

Regards
Matthias
