IRQ conflict causing DVD skipping

[Matt16978]

Here are my specs:
gf4 ti4200 w 30.82 drivers
audigy gamer (PCI 2) with creative driver updates
Linksys network card (PCI 5)
A7V266-E w/ Athalon xp 1700+
430 watt enermax ps
16x pioneer slot load atapi dvd drive attached with ata 100 cable
power dvd 4.0 xp with patch
windows 2000 sp3
also I have experimented with turning the "plug and play os" option on and off in the bios, with either setting still resulting in no change.
Also, I have just recently (4 hours ago) reseated all my boards.

Now for some reason, even though I know DMA is enablied for my dvd drive (enablied in registry and in device manager)
If I try to play a dvd (note: the drive works fine for reading normal data dvds and audio/data cds), the sound and video will get out of sync after 5 to 20 minutes (note these dvds work fine on my standalone, so I know that they are not the problem)
Seeing as how UDMA66 is enabled on the dvd drive, any bandwidth issue should be addressed. However, all my devices are on IRQ 9 (audigy, network, graphics) which would imply a irq conflict except for windows 2000 "virtual irq assignment"
Possible options left open:
1. Shift cards pci slots around and hope that that will change things (though in the mobo manuel, slots 2, 5 and agp don't share an irq)
2. Flash recent BIOS, hope it does whatever it will do

Please help me with any ideas

I had this problem using PowerDVD software... When I changed the sound output within the options of PowerDVD, it helped getting things in synch - I think I went from a 5.1, to a 2 speaker surround option or something. I think every once in a while (maybe every half hour?) I had to pause the movie, then resume it, but that usually fixed it. One night I spent downloading every DVD player one can find, and they all had their quirks. In one my speakers popped, in another there was no sound, another the picture sucked... I think overall DVD playback on the pc is just not where it should be. Try messing around with the sound output options though within the software... it should help a bit.

IRQ sharing is not your problem. In fact PCI/AGP devices do not even have IRQ lines! What you see in Device Manager is nothing but a number. Its only there for compatibility.


Have you tried a different DVD player? Like WinDVD?

In PowerDVD's Video options do you have the Hardware Acceleration button checked? If its alerady checked try unchecking it.

As the previous poster mentioned try all the different sound modes...
