Hi Hartmut, > Does the driver say the firmware revision is invalid after upload? > so similar to: > >>>tda1004x: found firmware revision 0 -- invalid > >>>tda1004x: waiting for firmware upload (dvb-fe-tda10045.fw)... > >>>tda1004x: found firmware revision 2c -- invalid no it was the corrected version: [kernel] tda1004x: found firmware revision 0 -- invalid [kernel] tda1004x: firmware upload complete [kernel] tda1004x: found firmware revision 2c -- ok I downgraded my kernel today to 2.6.9. but there is the tuning problem too. So i changed the antenna-amplifier. Now i have a better signal and the driver locks fast and on every channel again. Anyway, i think its a problem of the driver. When i had the first lock of a channel with the ?corrupted? amplifier, i got locks on all other channels as well. and the picture quality was nice. besides i detected that the card locks faster with QAM_64 modulation as with QAM_16 modulation, though the dvb-t provider says it is using QAM_16 modulation. regards, Marcel
