Hi Johannes,

thanks for your reply.

The budget card seems good now:

# dmesg
saa7146: register extension 'budget dvb'.
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 10
PCI: setting IRQ 10 as level-triggered
ACPI: PCI interrupt 0000:00:0e.0[A] -> GSI 10 (level, low) -> IRQ 10
saa7146: found saa7146 @ mem e0986400 (revision 1, irq 10) (0x13c2,0x1004).
DVB: registering new adapter (TT-Budget/WinTV-NOVA-C  PCI).
adapter has MAC addr = 00:d0:5c:01:d1:c5
DVB: registering frontend 1 (VLSI VES1820 DVB-C)...

and also
# ls -l /dev/dvb/adapter1/
total 0
crw-------  1 root root 212, 68 Jan  1  1970 demux0
crw-------  1 root root 212, 69 Jan  1  1970 dvr0
crw-------  1 root root 212, 67 Jan  1  1970 frontend0
crw-------  1 root root 212, 71 Jan  1  1970 net0

But still the premium card has no frontend ...

Right ->

case 0x0002: // Hauppauge/TT DVB-C premium rev2.X

                       av7110->fe =
ves1820_attach(&alps_tdbe2_config, &av7110->i2c_adap,
read_pwm(av7110));
                       break;

Unfortunately I don't understand this ... :-(

Well ...

frontend 1:
  tin box: ALPS TDBE2-031A
  frontend driver: ves1820
  demodulator location: ??
  demodulator: Philips VES1820 @0x09
  PLL: Mitel sp5659 @ 0x62

There's a TBE2-031A and a VES1820,
but I can't find anything that sounds like "Mitel sp5659".
I'm a boody greenhorn, I just don't know what to look for...

Best regards,
Armin
