Hi again,

Thanks to all who replied.
When looking around some more I found a quick and very very easy 
solution: kaffeine.
Kaffeine didn't display the DVB option at first. Only when I ran it as 
root. That's probably just a permissions issue.
It will automatically scan the whole satellite and it plays right away. 
And you can record with it too. Not yet tried, though.

Hi all,

I'm new to this group and I've got a few problems.

It took me quite some time to make my SAA1746 card (Hauppauge Nexus-S) 
work and be recognized a bit, because I had all the driver software 
installed in the kernel. That didn't work. Once I moved it to modules it 
worked. Sort of.

I can get to a free-to-air channel, which I use for testing, when using 
dvbtune and xawtv. I can see the channel (Though I have no sound, but 
that's not so important for now).
However, the channel turns black after a few seconds. When I relaunch 
dvbtume with the same parameters I get an image again.
Any ideas on what's going on here? The channel is NOT encrypted.

Second problem: How can I scan for channels and build a channel list? 
scantv doesn't work. If ends with the following display:
input = Television
norm = PAL

device has no tuner, exiting

But the default input is DVB, not 'Television' as per:
# v4lctl list
attribute  | type   | current | default | comment

norm       | choice | PAL     | PAL     | PAL NTSC
input      | choice | DVB     | DVB     | DVB
bright     | int    |     128 |     128 | range is 0 => 255
contrast   | int    |      64 |      64 | range is 0 => 127
color      | int    |      64 |      64 | range is 0 => 127
Horizontal | bool   | off     | off     |
Vertical f | bool   | off     | off     |

I read I could use 'vdr' to scan channels, somewhere, so I tried to 
start 'vdr' and I get the following.
$ vdr
vdr: no primary device found - using first device!

There's only 1 device - yet the error value = 2, so there's some problem.

I've come some way on my own, but hopefully someone can help me along a 
bit more, to fix some of the problems. Or at least point me to the right 
document that can help out.
