Hello!

Yes, I use it since about half a year now and all works fine, except the
remote and no auto tuning for radio yet.
It is all on the list and here was feedback for some known problems.

This might indicate that you have something different. The card in
question should be auto detected with tuner=54 at 0x61 and TDA8275A
hybrid silicon tuner. There is a prior version of the card with
different PCI subsystem IDs for which Asus recommends a firmware upgrade
to get all channels.

> dmesg tells me the frontend-tda100046H is up and running, I have tried all the dvb utils such as dvbtune, tzap, etc and have been using Kaffiene in an attempt to get channels as well. This shows, on occasion, signal and snr levels, but struggles to lock onto a signal. I have the correct transponder settings for my nearest transmitter.

Please post dmesg for relevant output of saa7133/tuner/tda10046a with
recent enough code, that we hopefully can find a explanation for your
troubles.

It should look like this.

Take care with the antenna input issue. 

I don't know what the XP driver does as default,
because I don't have any. Maybe you can also spy on the remote, since we don't even know the
address of the IR chip nor have it visible yet. An attempt to unsolder the tuner shielding was not successful,
guess I have to remove it mechanically otherwise the environment gets too hot.

Cheers,
Hermann
