I will do some rearch on that when I have time.

I did tried(urpmi, not yum) and found out I needed some other dep for
the upgrade, and don't want to break other stuff, oh.. forgot to
mention that I got a PVR500 about two weeks ago, Mandrake 9.2 freezed
when loading udev(I think that was it), so I decided to load new dist.
Picked fedora basically I am getting lazy. Well, with fedora, I only
can init one tuner on pvr500 and system crash(rebooted) after a few
minutes, complain about some address at 0x44, well I tired many
versions of ivtv, .2, .3.2, .3.4 and also tried daily release on .3.5,
gave up right before .3.6, it's still under devel I know they trying
to get it working, so I will let the PVR500 collect some dust on my
desk first. Anyway, I can say I am still happy with a pvr350 on the
master and a pvr250 on the slave.

I will nice things at different level next time to see how they
changes. I just tried to watch tv at 2200, I can see blocks, I can
tell the most when switching to a channel with some noise/snow, so
putting it back to 4500 made me happy.
Thanks again
