OK, thanks, I'll have a go at the Cab-CI; even if H.264 grabbing fails, I 
can still use the SDTV MPEG2 feeds as a second mythtv source.

However, I just noticed that my vendor wants to sell me a new version of 
the Cab-CI, a "2033 Mantis", on the Twinhan site here:

The board looks differently laid out, and the Windows driver package 
offered on the site is a different one from the old Cab-CI. I'm no expert, 
but this smells like a chipset change..
The only difference in the specifications on the website is that the 
Tuner's "Input terminal" changed from "Din-type" on the old Cab-CI to 
"F-type" on the 2033 version. But the driver download is larger by 10Mb!

Does anyone have any indication if this new version will work? Has anyone 
tested this new card under Linux? With CAM?
Or should I go hunting for a shop that still has the old version?
