There is a windows driver that comes with the system. Inspecting the 
3xhybrid.inf file reveals only tiny bits more information to me. Appears 
copyrighted by Philips Semi and is labelled "SAA713x Based - BDA TV 
Capture Driver" with a random provider name "Active Development Co., Ltd.".

Cards in the series are apparently called "Mercur, Tiger", "Proteus", 
"Europa (1-3), Snake, Tough, Smart, Clever" and "Europe (4.x)"

PHILIPS_33.DeviceDesc         = "PCI DTV Card"

... know it sounds strange (and indeed it is). It is inside an otherwise 
well-equipped enclosure of .cn origin that basically embeds a low-noise 
PC (GA-MA78M-S2H MB w/AMD X2 5400 CPU) inside what looks like a normal 
LCD based TV.

I don't think the signal is weak as such here, and it is also pretty 
random what channels fail. In tvtime, I can sometimes just roll through 
the inputs (tuner, composite, ...) and then the signal is there when the 
tuner is re-selected. More likely some card specifics that needs to be 
added, me thinks.

This is not evident. The specs on the device leads me to think that 
there is at least DVB-T support, but I'm not sure.

OK -- so likely some setup missing too.

Full log is temporarily here:

   http://www.b4net.dk/dmesg.log2

There is also a http://www.b4net.dk/dmesg.log when run with my "normal" 
parameters for getting the card somehow working. Sometimes, randomly (as 
in the log above) there is a also a whole slew of dsp errors, which 
again points in the direction of some setup failing.


Thanks for any advice you can give!
