A hybrid DVB-T PCI card from KWorld.

It is supported under Linux.

Note: The device is also resold by Tevion as the DVBT-220RF.

Overview/Features

The linux driver seems to work better than the Windows driver, and the users would like to thank the development team for providing such an excellent driver for this budget card.

Components Used

The second revision of this card is based on SAA7131E chip (Autodetect don't work)

Making it Work

Firmware

Drivers

This card is automatically detected by a standard modern linux kernel and it card seems to be well supported.

Note: on older kernels (e.g like with Ubuntu 7.04 or less) digital (DVB-T) support isn't enabled because saa7134-dvb is not loaded automatically (To enable this run 'modprobe saa7134-dvb' as root).

NOTE: Getting it working on older kernels (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.
