Hi, Marcel Hm, that's not what i expected.. The tda1004x module has undergone guite a lot of changes, i guess most of them with thr tda10046 in mind. I still think that the firmware upload fails at the first attempt. This might just be a timing issue in the initialization. please try a recent version of the module from the dvb-kernel cvs at linuxtv.org. If this doesn't help and noone else can help you, you might send me the last version of the module that worked. Sorry, I have no better reply Hartmut
