Hi, I have latest 2.6.12.1 with patch provided by linuxtv.org. Two Terratic Cinergy 1200 DVB-C cards are identified correctly according to dmesg: <snip> saa7146: register extension 'budget dvb /w video in'. ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 5 (level, low) -> IRQ 5 saa7146: found saa7146 @ mem d0956000 (revision 1, irq 5) (0x153b,0x1156). DVB: registering new adapter (Terratec Cinergy 1200 DVB-C). adapter failed MAC signature check encoded MAC from EEPROM was ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff budget-av: ci interface initialised.

ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 12 PCI: setting IRQ 12 as level-triggered ACPI: PCI Interrupt 0000:00:0b.0[A] -> Link [LNKD] -> GSI 12 (level, low) -> IRQ 12 saa7146: found saa7146 @ mem d0958000 (revision 1, irq 12) (0x153b,0x1156).

It simply doesn't lock to signal. Plugging the same cable with the same signal to adapter1 gets adapter1 tuned correctly. Where is the problem? thankx michal
