Hi Konstantin, It seems that you are right. The tuner is actually TDA8274, not TDA8264. Sorry for the typo. Looking at other drivers like the saa7134 one, it seems that there may be more work to do to get the TDA10048 to work. Also, the demod TDA10046 has special code to work with this tuner. I'm wondering if the same applies for TDA10048. Unfortunately, I'm kinda stuck right now. Maybe the next step would be to sniff what the windows driver sends via USB but I don't have any windows install to try with. Any suggestions ?
