I use that card quite successfully, BUT only with the addition of the patch
from the linux-dvb list that I will drop in below. This patch to the xc5000
tuner module (that this pinnacle card uses) has been available since late
January of this year. Word was that it would be included in the mainline
linux-dvb "probably in the next few weeks" but that has not happened. I'm
not sure why not.
Here is the patch that resolved the issues you seem to be having from me.
Thanks again to Mr Zhang.
P.s. here is a link to the archive of the patch
http://www.linuxtv.org/pipermail/linux-dvb/2008-January/023392.html

I just noticed that the previous patch that fixed the kernel oops has been
merged into the master tree, which conflicts with the patch for tuner
performance improvement(which contains the oops fixes too). I regenerated
the patch against the master tree and it is below. Please use this one
instead.
