[-- Attachment #1: Type: text/plain, Size: 409 bytes --]
The patch adds support for SDMC DM1105 PCI chip. There is a lot of
cards based on it, like DvbWorld 2002 DVB-S , 2004 DVB-S2
Source code prepaired to and already tested with cards, which have si2109,
stv0288, cx24116 demods. Currently enabled only stv0299, as other demods are
not in a v4l-dvb main tree, but I will submit corresponded patches (si2109,
stv0288) next time.
Best Regards
Igor M. Liplianin

+ Support for cards based on the SDMC DM1105 PCI chip like
+ DvbWorld 2002
+
+ Since these cards have no MPEG decoder onboard, they transmit

+ an external software decoder to watch TV on your computer.
+
+ Say Y or M if you own such a device and want to use it.
