A hybrid DVB-T PCI card from Medion.

This Medion CTX 953_V.1.4.2 DVB-T/analog hybrid PCI-card (P/N 2003 2576) came with the ALDI-machine described here.

Hardware

It uses the following chips:

NXP SAA 7131E/03/G
CH1394
SF8510.1
TSG 07172

NXP TDA 10046A
SF9349.1
256
07151

NXP 8275AC1
CMOS 38
TP607111

Running the command # lspci -v yeilds:

05:01.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d1)
        Subsystem: Creatix Polymedia GmbH Unknown device 0010
        Flags: bus master, medium devsel, latency 64, IRQ 22
        Memory at ff9ff800 (32-bit, non-prefetchable) [size=2K]
        Capabilities: [40] Power Management version 2

and # lspci -vn:

05:01.0 0480: 1131:7133 (rev d1)
        Subsystem: 16be:0010
        Flags: bus master, medium devsel, latency 64, IRQ 22
        Memory at ff9ff800 (32-bit, non-prefetchable) [size=2K]
        Capabilities: [40] Power Management version 2

The card has an S-Video IN, an Audio-IN (3.5mm), and a Composite-IN.

Support

Both analog and DVB-T work fine on Linux. This card seems to be based on the TIGER-S design with external LNA, which is "card=109". A firmware does not seem to be required. I bought 10 of these and one tries to load a firmware and sometimes succeeds, but it can't tune anything - it's probably broken.

If it IS needed, either use the updated get_dvb_firmware script or use the file "TT_PCI_2.19h_28_11_2006/software/OEM/PCI/App/ttlcdacc.dll" contained in http://technotrend-online.com/download/software/219/TT_PCI_2.19h_28_11_2006.zip, which you'll have to rename to /lib/firmware/dvb-fe-tda10046.fw.

You can also get an archive with several firmwares including dvb-fe-tda10046.fw: DVB firmwares v2, 7Z–728 KiB, TBZ–1.80 MiB, or ZIP–2.08 MiB, contains 114 files.

Generally, you should read http://article.gmane.org/gmane.comp.video.video4linux/34255.

RF remote control

ALDI also sold a remote bundled with the computer mentioned above. It is NOT connected to the TV-card, but rather sends its RF-signals to an X10-USB-receiver.

The remote works nicely using lirc-0.8.2 or higher (0.8.1 does NOT work correctly, you have to press most keys twice because of a missing "toggle_bit_mask"-setting). The modules lirc_atiusb and lirc_dev have to be loaded. Make sure that the kernels atiusb and atiusb2 modules are NOT loaded (don't compile them), they don't work.

This is the lsusb info about the X10-USB receiver: "Bus 003 Device 002: ID 0bc7:0006 X10 Wireless Technology, Inc."

lirc
