Steve,
           I think we are talking about two different things. Yes the 
xc3028 tuner is supported via tuner-xc2028 and works for many xc3028 
based cards. This support uses the xc3028-v27.fw file that contains say 
80 firmware modules. This firmware was extracted from a Haupage windows 
driver.

I believe that the 1800H has some incompatibility with this firmware. 
The mcentral.de tree has a different firmware loading and tuner support 
module for xc3028 that loads individual firmware modules - you literally 
put twenty or thirty files into /lib/firmware. This firmware is the 
standard firmware from xceive before the card manufacturers get to it. 
Comparing the dmesg listing from a working mcentral.de setup and the 
non-working v4l tree the only thing that leaps out is the different 
firmware. If I was continuing the next step would be to port that tuner 
module into the v4l code and set it up in the normal way.

Cheers Paul
