[QUOTE="RaStr, post: 10680"] [b]AVER T771 & DVICO drivers[/b] Hi all, I've been playing with DVICO drivers and my Aver card about a week. Till now, I have the following results: 1. It is not a problem to make the drivers load and initialize 2. The DVICO drivers use the I2S serial interface to receive TS stream data, while my T771 uses parallel mode 3. The BDA driver is actually a wrapper to WDM driver, not a native BDA 4. The WDM driver is derivate of generic BT878 TS driver and is configurable via registry (at least seems to be, I have not tested this yet), so I have patched the .inf file accordingly 5. The tuner device (tin box) uses Infineon's PLL TUA6034, which seems to be compatible with Thomson's T7579 used on original DVICO card, only I2C address differs, but this is again selectable by patching the .inf 6. The DVICO's codecs and apps. are protected and actually the protection is based on the content of EEPROM content on the board, I can make some app. to overwrite the original EEPROM, but need to know the content of some "generic" dvico card, anyhow this is not so important to me for now, as I can use other drivers and software if BDA will work ! 7. Yesterday I have finally made my I2C communication sniffer and started capturing the data on the card during channel scan. Suddenly I have had only limited lite version of capturing application available yesterday, so I was unable to capture the full sequence, but from what I have seen it is obvious that the drive is switching the OFDM decoder to serial data output ! 8. I will continue today, but it seems to be pretty sure, that it cannot work until the driver will be patched on the software level, and I am not a good code cracker, so I am afraid that there will be no progress if I will not get the driver source, which is highly improbable ! Anyhow I will give it another try and I will capture the I2C commands from Aver's software for compare too, so wish me enough strength (I have been sleeping only two hours today because of that) and good luck !
