[linux-dvb] Analog capture (saa7113) not working on KNC1 DVB-C Plus (MK3)

["L." <IxAYMzFpK2ojlw@sofortsurf.de>]

Hello,

with a KNC One "TV-Station DVB-C Plus" PCI card (MK3 - Philips SAA7146
with CU1216L/A I G H-3 Tunerbox with TDA10023) equipped with composite 
and s-video inputs ('Plus' version, Philips SAA7113), analog capture 
is not working. Most recent kernel sources I tested were 2.6.25-rc7.

DVB-C television works fine with this card using 'budget_av' kernel
module (from kernel 2.6.20 on, using e9hack's tda1002x patch, and
later with mainstream kernel sources alone), but when opening an
analog input, there are no data coming. A black screen is shown with
'xawtv' application. Xawtv correctly shows up the two video sources
this card provides: 'S-Video' and 'Composite'. 

I checked the cables and video sources, they work fine with another
card with analog input.

I can do tests or compile something if you want me to. Information from 
lspci, dmesg and lsmod please see below. Help to get analog capture
working is appreciated very much.

Thank you

L.
