Hartmut and Hermann,

ok, I got out the manual and will try to describe the card as good as I can.

The card in question is a PCI DVB-T TV (analog) FM Tuner card named Vivanco 
21056 (the cardbus version is called 21057). The description claims parallel 
processing of DVB and analog signal with picture in picture resp. 
split-screen capacity.

It has a combined DVB/Analog connector, an FM connector and one further 
connector for a combined AV cable with connectors for Composite, S-Video, 
Audio L/R and IR Remote. The card doesn't have a second Composite input, 
contrary to what TVTime suggests, there is a connector on the card just next 
to the AV connector, which seems to provide these interfaces, maybe for the 
front panel.

I haven't bothered trying FM under Linux, but under XP it works. S-Video works 
under Linux and XP. As mentioned earlier, analog works only for one frequency 
which is Channel 12 (here: FAB)

Now for the chips: the big three Philips are (a slash indicates a new line)

- SAA7131E / CE0957 / S37513 / T-N05101
- TDA10046A / SA6724-1  06 / ZSG 05111
- 8275AC1 / P1M48 / 01 / cPG05131

The one you mentioned (between antenna and 8275):
- 4231 / 0761 / 433
it doesn't seem to be directly connected to the 8275. Rather to the 7131, but 
I can't tell that exactly. I am not an expert.

Here's a few other chips
- top middle: LV4052 / AR245 / UnG05 / 12C
- a bit right, left of the TDA10046A: ATMEL 508 / 24C256N / ??U27 B
- right of the TDA10046A: RM18B / R133AL
- further down, just upper right to the 7131: ATMEL 516 / 24C02N / SU27 D
- to the right, at the right edge: PIC16C505 / -041/SL / 050838A
- further down: LD1117A / L33ASA, further left (left of the 7131) there is 
another one

Hopefully this information is of any use to you.

Kind regards
Werner
