So was the crappy power-supply the root of all your troubles, or have you had 
other problems as well? I guess the cards ain't some kind of magic device 
which can filter away noise from a crappy psu, hmm? Keep in mind that it's 
receiving fairly high frequencies, and noise is not it's best friend.

I had a problem with a mainboard a long time ago, but that was solved by a 
bios upgrade.

I belive it takes main profile 1 and 2 or something like that, limited to the 
resolutions of the DVB standard (704x480 + 720x576 + 352x240 + 360x288, or 
something like that). Someone more experienced in this area could probably 
tell you more, but the archive 
(http://www.linuxtv.org/mailinglists/linux-dvb/) would probably contain the 
info you are seeking.
