The HDHomeRun works fine for me, but so do the pcHDTV cards.
If you search the MythTV mailing lists for 'setpci' you should be
able to find some HOWTO's on setting the PCI latency, which I
believe should work except that some chipsets do not allow you
to change the latencies. In that case only a new motherboard
will solve the problem. You might also want to check dmesg, a
failing hard drive or CD-ROM drive will sometimes swamp the PCI
bus, but in that case dmesg should be giving you error messages.
