[linux-dvb] v4l2 interface seems not to work

Hi all,

I have just touched DVB-S since one week ago. I have a
Hauppauge WinTV Nexus-S rev2.2 card, while having
Redhat Enterprise 3.95 installed on a DELL Precision
670 workstation. Now I use Linux kernel 2.6.11.6 with
DVB modules selected.

I modified the udev configuration so that
/dev/dvb/adapter0/* are all generated correctly, while
I downloaded and placed the firmware into
/lib/firmware as dvb-ttpci-01.fw.

Then I created a initial-tuning-data file to scan
channels with dvbscan based on Asiasat3S-105.5E
transmitter. Many channels are found, so I use szap to
select one channel I would like to watch.

However both mp4live and xawtv, based on v4l2 API, do
not work. Nothing can be seen except of blank screen.

So can anybody help me? Below is the log relevant.

Thanks.
