The one closer to the motherboard is marked CATV-IN on mine. (1043:4862)

The upper one is marked RF/FM-IN here.

With the patch in mercurial master now this is correct. It won't work
anymore on the analog/CATV at all. So it seems that the same switch on
your card (1043:4876) happens too.

That's the confusing part for me on your card. For what I found on mine
using radio once does exactly the same as the gpio21 switch now in
asus_p7131_dual_tuner_init in saa7134-dvb.c. Every time a dvb app uses
the tuner the antenna switch happens. Also adding a .mute section
with .gpio 0x0200000 did the trick from the analog side previously.

Previously both were possible, the one marked here RF/FM-IN only after
using radio first. Now with the patch in mercurial master and 2.6.19
DVB-T on mine is always and only at the RF/FM-IN.

No problem. Maybe something is different and within the ongoing changes
it is easily confusing anyway. Sorry.
I was up to test again, but after a while realized that DVB-T on the
card is broken currently ...
Also in your case note the new function name introduced with the
Pinnacle 310i patch to get the firmware.
static int philips_tda1004x_request_firmware(struct dvb_frontend *fe,
const struct firmware **fw, char
*name)
{
struct saa7134_dev *dev = fe->dvb->priv;
return request_firmware(fw, name, &dev->pci->dev);
}
But first we need to have the card working again. Patch attached.
Hartmut, would you please pick it up?
BTW, thanks for the radio signal and stereo detection!
Cheers,
Hermann
