Your problme seems to be pam bug, maybe.
Using sudo and replay comment on FedoraBug 195914.

This is not a permissions issue. I can tune the USB DVB card - even as a normal user (even though I normally use root for DVB access.

# tzap "7 Digital"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 177500000 Hz
video pid 0x0301, audio pid 0x0302
status 1f | signal 4d4d | snr f0f0 | ber 000000fb | unc 00000000 | FE_HAS_LOCK status 1f | signal 4e4e | snr f0f0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal 4e4e | snr f0f0 | ber 00000000 | unc 00000600 | FE_HAS_LOCK

However, if I use the following:

vlc dvb: --dvb-frequency=$1 --dvb-bandwidth=7 --dvb-hierarchy=0 -- program=$2 --intf=dummy --sout $transcode:$output

where:
$1 = 177500000
$2 = 1328
$transcode = "#transcode {vcodec=mpgv,mux=pes,vb=2048,scale=0.5,acodec=mpga,ab=128,channels=2,dei nterlace}" $output = "standard {access=http,mux=ts,url=203.56.246.82:8080,name=unicast}"

Then no output comes from the card - although it does tune and the frontend does get lock.

This exact same command line works in kernel 2.6.15-1.2054_FC5. This leads me to believe that it's a kernel issue I'm dealing with - although I will try any other suggestions!

I have uploaded the debug output of vlc as an example of a non- working output, and a working output using the FC6 kernel vs 2.6.15-1.2054_FC5.

Non-working FC6 kernel:

Working 2.6.15-1.2054_FC5 kernel:
http://www.crc.id.au/files/2.6.15-1.2054_FC5.txt (14Kb)

As you can see, there's a big difference. You can ignore the tuning errors in the FC5 one - I just need to move the antenna into a better location - I do actually get video :)
