for what I seem to know so far, it has a saa7135 with 32.110MHz
audioclock. The digital demod is tda10046 at 0x08 with firmware eeprom.
The 16MHz clock comes from a tda8275ac1 used for DVB-T tuning at 0x60.

A second tda8275ac1 at 0x61, also 16MHz clock, has a tda8290 analog
demod at 0x4b also used as i2c gate for analog tuning.

You could give the Tevion/KWorld DVB-T 220RF card=88 a try.

Is not completely the same design. That one uses a saa7131e, has radio
and a KS700 remote controller, which yours seems to miss.

Does it have a fan for cooling? Hopefully not.
It is likely that external analog audio-in is on amux Line2 and not on
LINE1 like on card=88 currently, not sure about it.

Don't use overlay preview mode with the fglrx. Also, depending on that
binary driver, I can't say if you can have multiple VideoOverlays for
DVB-T and analog TV at once, which the card itself does provide.

In case you should ever get something at all ;) to work, if DVB is
running you can't use/record analog TV with planar formats at once, like
mencoder will use them by default. That might end up in corrupted files
on the disk, due to dma limitations. You need to force packed formats
for such analog operations simultaneously.
Some shots in the dark.

All related stuff reloaded with the saa7134 option i2c_scan=1 ("modinfo
saa7134") might help to find out, how dark it really is.

Good Luck,

Hermann
