Some are for analog TV only, some only for DVB-T or DVB-S, most are hybrid for analog and DVB-T, some have support for analog, DVB-T and DVB-S. Some have dual tuners and can provide analog TV from tuner and DVB-T at once or alternatively DVB-S. The Medion Quad(ro) (CTX944) with two saa7131e can provide up to four different TV streams from tuners at once, combinations of dual analog TV, dual DVB-T and dual DVB-S and has also additionally external composite and s-video inputs, but needs at least a dual PCI capable slot. (blue colored on MSI motherboards, original slot is green and supports also the modem it has) To give some idea of the cards around so far. The information of how the cards are configured is mostly stored in saa7134-cards.c and saa7134-dvb.c. Most follow more or less closely various Philips/NXP reference designs, some have special solutions which might be difficult to discover. The saa7131e is detected like also the saa7135 as an saa7133, but has an build in tda8290 anaolg IF demodulator, usually at 0x96, which in most hybrid cases also works as an i2c bridge for the tuner programming. Most common these days are tda8275a hybrid silicon tuners and for DVB-T tda10046a channel decoders. A still popular reference design for these is card=81 (saa7134.h), the Philips Tiger, but there is also already the Tiger-S, which has an additional external LowNoiseAmplifier which needs to be properly configured. Please examine the card closely, even the smallest chip has its meaning and also what is written on the clocks/xtals. The same goes for the printings on the board, maybe it is some OEM version of an already known board. Also posting to the video4linux-list as well might bring you more feedback. A first try might be to modprobe -vr all related modules and "modprobe -v saa7134 card=81 i2c_scan=1" , if it should be something in the near of that one. Read the v4l wiki at linuxtv.org about adding new cards.
