Sam, that URL requires a password... Anyway, I find this bit
interesting since the conexant based hybrid cards worked well
in 2006 and early 2007, but then began acting funky and requiring
driver module parameters to work at all. Maybe there is a single
easily revertible patch breaking both MPEG recording, and
analog<->digital switching on hybrid cards?
