I ran into the exact same thing wiht my ATSC 110s. If you look at the
linux-dvb mailing list from linuxtv.org you'll see a thread about the same
topic recently. So far no one has come up with a resolution.
I ended up lucking upon a free 4 slot pci motherboard (seeming to be a
rarity these days) and just dropped in two PVR-150s. Please post back if
you find a fix!
