TV karta Technotrend Budget S-1500B problém s naladěním některých kanálů

Dobrý den.

Chtěl jsem zakoupit TV kartu s podporou v Linuxu (Debian Squeeze). Koupil jsem tedy Technotrend S-1500. Bohužel jsem zjistil, že to je nástupce s označením S-1500b:

03:01.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)

Subsystem: Technotrend Systemtechnik GmbH Device 101b

Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-

Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-

Latency: 32 (3750ns min, 9500ns max)

Interrupt: pin A routed to IRQ 17

Region 0: Memory at fa100000 (32-bit, non-prefetchable) [size=512]

Kernel driver in use: budget_ci dvb

root@pc-tv:~# dmesg | grep DVB

[ 5.400994] DVB: registering new adapter (TT-Budget S-1500B PCI)

[ 6.352337] DVB: registering adapter 0 frontend 0 (ST STV0288 DVB-S)...

[ 11.040165] dvb_ca adapter 0: DVB CAM detected and initialised successfully

Našel jsem, že tento nový model potřebuje patch:

http://www.dvbshop24.com/index.php?topic=9249.0

Zkompiloval jsem tedy nový kernel z backports (3.2.9) a nové V4L-DVB ovladače (git clone git://linuxtv.org/media_build.git). Pokud to dobře chápu, tento patch je již v aktuálním kódu V4L-DVB obsažen (porovnával jsem zdrojové soubory).

Stále mám ale problémy naladit některé transpondéry:

Napříkad:

root@pc-tv:~# szap -c upc_channels_all.conf "CT 4" -H

reading channels from file 'upc_channels_all.conf'

zapping to 10 'CT 4':

Některé bez problémů:

Nemáte prosím někdo tuto kartu zprovozněnou.

Děkuji.

Truhlář.
