KWorld DVB-T 220

Status

The Tevion/KWorld DVB-T 220RF is a digital + analogue PCI card and is automatically detected by a standard recent linux kernel.

This card seems well supported although digital (dvb-t) support isn't enabled automatically. To enable this run 'modprobe saa7134-dvb' as root.

Bugs

Getting it working on older kernels

NOTE: This should no longer be necessary for any recent linux distribution

In linux 2.6.16, the Mercurial version of v4l-dvb was required. See the second last post at http://forums.gentoo.org/viewtopic-t-449615-highlight-kworld.html. The gist is that you don't use the DVB modules from the kernel, but install the modules from the Mercurial version of v4l-dvb and use those instead.
