Hello everybody,

I've been trying to get my recently (yesterday) bought dvb-c tuner working
under Ubuntu Hardy. Installed drivers from http://www.jusst.de/hg/mantis,
and the /dev/dvb got populated, but without frontend.

Output from lspci:

administrator at hydra:~$ lspci -d 1822:4e35 -vv
00:08.0 Multimedia controller: Twinhan Technology Co. Ltd Mantis DTV PCI
Bridge Controller [Ver 1.0] (rev 01)
    Subsystem: TERRATEC Electronic GmbH Unknown device 1178
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
    Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort+ <MAbort- >SERR+ <PERR+
    Latency: 32 (2000ns min, 63750ns max)
    Interrupt: pin A routed to IRQ 20
    Region 0: Memory at fc020000 (32-bit, prefetchable) [size=4K]

PCI id seems to have changed from the earlier Cinergy C cards.

 Output (partial) from dmesg:

Even I managed to notice one line stating: "!!! NO Frontends found !!!", so
I guess it's no wonder it isn't working.

Does anyone have a clue what I should try next? Or has anyone had success
with this card. I couldn't find earlier models, like cinergy 1200-c, or even
newer, anywhere. I'm supposed to build a DVB to IP streaming machine for a
school, so I would also be happy if someone knew any other available DVB-C
cards working under linux.

Best regards,
