using vanilla kernel 2.6.15 I fail to get a recent Hauppauge Nova-T
board to work. The board is DVB-T 9002 Rev. C176 using the Conexant
Tuner CX22702-15 and Decoder CX23882-19.
All relevant modules seem to be loaded successfully:

I even got the remote control to work with LIRC. But when I start a
viewer application I only get the sound but no picture. Also, the
following message sequence floods my syslog as long as the application
is running:

xine is buffering up to 100%, but then only shows coloured noise.
klear (self-compiled from http://www.klear.org/) crashes. I may switch
channels using xine and tzap, and the audio is switched successfully.
Strangely enough I had some success with both klear and xine yesterday
using self-compiled Debian Kernel 2.6.12. which gave me video and
audio, but today I only get the same application results as above, but
a different entry in the syslog:
Jan 5 12:44:42 dt2ix kernel: cx22702_set_tps: Autodetecting
Jan 5 12:44:44 dt2ix last message repeated 7 times
Jan 5 12:44:45 dt2ix kernel: cx88[0]: irq mpeg [0x100000] ts_err?*
The message containing 'cx22702_set_tps: Autodetecting' appears very
frequently, whereas the one with 'irq mpeg [0x100000] ts_err?*'
appeared only once. Nevertheless, here is my /proc/interrupts

Any hint would be appreciated since I am running out of ideas.
