[QUOTE="RaStr, post: 10717"] [b]I2C address[/b] I am not sure if this will be enought, there are two bytes of configuration for a PLL chip and those have to be checked with the data comming out from Aver driver (as I have not datasheet for a tinbox and some of the PLL parameters depend on the PCB layout, etc.) and finally there is the problem with data transfer mode (serial vs. parallel), but if the PLL will opereate the mt352 have to lock on the channel and this will be indicated by the driver. I have spent three hours now looking at the DVICO's code, I expect that "our" part will be in the zulutune.sys, I have found something, which seems to be an initialisation according the registry, but there is no C0 anywhere there :( , which corresponds to my assumption that it is hardcoded somewhere else in the driver. There is one more problem I have found yesterday, I have used ScanChannelsBDA.exe for a test and I have entered 506000kHz as a frequency and 8Mbps as a bandwidth, but in the sequence I have captured were data for a 7M bandwidth, but I am not sure it this is not a problem within the ScanChannelsBDA.exe itself or not.
