Thanks Craig,
I just learn a lot in the last few hours. My system mostly uses
PCI-express. The on board SATA, IDE, ethernet, and nVidia 6200 card are
all PCIE. So, according to this thread:
http://www.gossamer-threads.com/lists/mythtv/users/272818
I don't need to worry about pci latency because the concept really
doesn't exist with PCIE.
I did try to change the latency but it alway returns a latency value of
0 except on the two PCI PVR-150 cards I have.
Thanks,
Jon
