[mythtv-users] Strange glitches/pops

[Cory Zerwas]

Any news on this?  I am running FC4 with 2.6.13-1.1532 i686 (Athlon XP 32
bit CPU) with a PVR-350.  It seems this started to occur after I installed a
RAID adapter for extra storage (3ware 7500 series, 8 port).  Could this be
the issue?  Also, what do I have to change in linux (if anything) when I
change the IRQ either in the BIOS or by moving slots?

I am seeing about 5-6 errors per second, looks exactly like the example.

And what's going to happen when I pop this fancy PVR-500 in there?  More IRQ
sharing issues?
