Second DVB-T card

[kakariko81280]

I am trying to set up a MythTV box and it has all been going very well until I've tried to add a second tuner card.

I'm using two Hauppage Nova-t terrestrial digital decoders. Identical models.

The relevant output from lspci

00:0b.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
        Subsystem: Hauppauge computer works Inc. Unknown device 9002
        Flags: bus master, medium devsel, latency 32, IRQ 20
        Memory at e5000000 (32-bit, non-prefetchable) [size=16M]
        Capabilities: [44] Vital Product Data

00:09.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)
        Subsystem: Hauppauge computer works Inc. Unknown device 9002
        Flags: bus master, medium devsel, latency 32, IRQ 19
        Memory at e2000000 (32-bit, non-prefetchable) [size=16M]

Both cards work if they are in the machine by themselves but when they are both in at the same time, one of them can never get a lock when it is being tuned in.

I am using Mythbuntu. It automatically set up the tuner cards with the cx8802 driver.

Any suggestions?

Bump.

I'll take anything, even if it's only "It works for me!"
