Hi,
i'm having problems with my new DVB-C device on UPC DVB-C network
(Bratislava, Slovakia, encrypted using Conax CAM module inserted in CI
slot connected to the DVB-C card):
05:00.0 Multimedia controller [0480]: Philips Semiconductors SAA7146
[1131:7146] (rev 01)
Subsystem: KNC One Device [1894:0022]
Flags: bus master, medium devsel, latency 64, IRQ 16
Memory at ff700000 (32-bit, non-prefetchable) [size=512]
Kernel driver in use: budget_av
Kernel modules: budget-av
As you can see, the device is detected and modules loaded :

The problem is that i can't even successfully scan for channels.To
rule out hardware issue, first i tried to use it first with my Windows
PC, it worked flawlessly (SD absolutely no problems, HD channels had
some minor dropouts due the high bitrate). The result of scan for
channels using GlobeTV (the Windows app) was this :
http://pastebin.com/XNHvjAfb .
Because i'm using a cable operator not listed in /usr/share/dvb files,
i need to use w_scan and the result is something like this :
http://pastebin.com/0fUS6Tzx .
Because of those filter timeouts, it finds no channels using the same
cable and card which had no problems on Windows and using the same
cable which has no problems with the provided set top box from the
cable operator.
You might suggest me to use dvbsnoop, but only two commands which work
are the signal and feinfo. pidscan returns nothing :
# dvbsnoop -s signal

Device: /dev/dvb/adapter0/frontend0
Basic capabilities:
Name: "Philips TDA10023 DVB-C"
Frontend-type: QAM (DVB-C)
Frequency (min): 47000.000 kHz
Frequency (max): 862000.000 kHz
Frequency stepsiz: 62.500 kHz
Frequency tolerance: 0.000 kHz
Symbol rate (min): 0.451875 MSym/s
Symbol rate (max): 7.230000 MSym/s
Symbol rate tolerance: 0 ppm
Notifier delay: 0 ms
Frontend capabilities:
auto inversion
FEC AUTO
QPSK
QAM 16
QAM 32
QAM 64
QAM 128
QAM 256
Current parameters:
Frequency: 362000.000 kHz
Inversion: ON
Symbol rate: 6.900000 MSym/s
FEC: none
Modulation: QAM 64
Tested using Arch Linux 2.6.37-ARCH and current 2.6.39-rc3 kernels,
same result.
Signal level according to the set top box is ~57%, signal quality is
97-99%, and as i mentoined, set top box works without problems, and
it works using this DVB-C card and same cable when using with Windows
(but true, on different PC).
Any ideas ?
PS: I hope this mailing list is the right one for my issue.
