But I have some questions. No, it doesn't help DVB at all.

I have the P7131 Dual still fine for analog after two passive splitters on cable-tv and it can still easily compete with a FM1216ME/I H-3 (MK-3) Philips tuner under the same conditions, which I consider to be my best one, but adding a third splitter will be too much. I think it is not card specific. Analog requires cable-tv signal quality input, at least there was nobody satisfied yet with FTA analog. (I don't know if there could be a specific UHF range problem too, like it may occur in the UK, since we don't have reception there) > Second, is there any further and better patches to be applied to the Asus? Patches are welcome, you would need the gpio switch in card specific digital tuning code to make it persistent from this side. > Last but not least, is there any way I get get TV, DVB and radio all working, with only > one airial as it has two inputs, one for DVB/FM, and the other for analogue. I notice > the patch above disables FM. No, the mute /abuse patch does not disable radio. If you consider all possible combinations, there is no ideal solution for what I can see. On a certain point you have to plug antenna connectors. That's why I leave it as is for now, but patches are welcome ...
