I've not seen anything specific on the linuxtv.org website (had checked 
before selecting the cards and have checked on a regular basis the 
website for any updated info). I also tested with rev 2.6D (currently 
the latest hardware version) and I have the same issue.

This is the output since the launch of the process a week ago. Verbose 
was not enabled because there usually is too much data being outputed 
when I'm running in non debug mode.
