The website says it can do both digital and analogue, the paper manual
says it only does digital, so without spending some time trying to find
a tuner the kernel can talk to I really can't be sure. Even if we
skip that for the moment, the DVB-T200 v4l struct currently doesn't even
mention that the card has a TV input. According to the website, all
the DVB-T2* cards have TV input, though the T220 doesn't have a
composite input.

Don't know if it works yet, as I've not got far enough to tell. I'm
guessing it's unlikely to be able to autodetect this card. Here's the
dmesg output:
ACPI: PCI Interrupt 0000:00:0f.0[A] -> GSI 18 (level, low) -> IRQ 185

The paper manual has a small label stuck to the bottom corner of the
first page that says "VS-LTV883RF" so it seems like a good bet combined
with the information from the packaging claiming that V-Stream is a
trademark of KWorld.

Hmmm:
[root@hallertau ~]# modprobe saa7134-dvb
[root@hallertau ~]# ls /dev/dvb
ls: /dev/dvb: No such file or directory
[root@hallertau ~]# modprobe cx88-dvb
[root@hallertau ~]# ls /dev/dvb
ls: /dev/dvb: No such file or directory
Should udev be creating these? I have it in debug mode atm, so I can
try to work out what's going on.
