[mythtv-users] Both revisions of the Nova-T in one backend (DVB problem rather than mythtv, sorry)

[Graham Wood]

Hiya - I've had a quick look at the archives (and google), but can't 
seem to find anything relevant...  Apologies if I've missed a relevant 
thread and I'm also more than happy to be told a better place to ask if 
there is one.

I've just upgraded my machine from Debian sarge to Debian sid - with the 
associated kernel upgrade, and also have installed mythtv 0.19 (from source)

I did this because I have just purchased a second Nova-T card, and now 
have one of each revision in the box:

0000:00:08.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI 
Video and Audio Decoder (rev 05)
0000:00:08.2 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and 
Audio Decoder [MPEG Port] (rev 05)
0000:00:08.4 Multimedia controller: Conexant CX23880/1/2/3 PCI Video and 
Audio Decoder [IR Port] (rev 05)
0000:00:09.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)

Sarge (debian standard 2.6.8-2-k7):
    Old card works fine with the grundig  frontend driver
    New card doesn't get detected as a DVB (cx8800 fails to ID the card)

Sid (debian standard 2.6.15-1-k7):
    Old card is installed using the L64781 frontend driver, and cannot tune
    New card works fine with the cx88 driver.

Attempting to use tzap:
tzap -a 0 -f 0 BBC\ ONE

and the snr just keeps cycling...

Anyone got any advice?
