All 5 of the PCI slots on the ASUS A7V266E mainboard are supposed to
be Bus Mastering PCI slots (V2.2 compliant). Only PCI slot 4 is IRQ
independent. All of the other slots share an IRQ with USB, the AGP
slot, or IDE controllers.
I moved the HDTV Wonder card to pci slot 4, device manager in windows
confirms is has IRQ 10 all by itself, and I see no difference in
performance or behaviour in any of the slots on this computer. The
highest CPU usage is 50% on an athlon 1900+.
1080i channels are still audio only. Could it be an issue with AMD
chips or a VIA chipset?
I think it’s related to driver or encoder issues. Even the WatchHDTV
program I downloaded shows 1080i channels to have no picture, not just
with DTV.
