Guys, I lost track of this thread. I've had my AIW 9600 128 for quite some time now and it's in my 2nd computer. I use it all the time to capture gameplay and make movies and such. That system is comprised of the following: Windows XP Home SP2 -- all the updates. ABIT BD-7 Mobo, P4 1.6 GHz, AGP 4X, 350 W PSU, 1 GB PC2700 RAM, and several HDDs, 2 CD/DVD Drives, and other things. I know it's no consolation just to say that it's working flawlessly for me under these circumstances. Yet, it IS working just fine. One thing I do notice is that my AIW is isolated on its own IRQ in Device Manager. In this case, it's IRQ 16. Since someone brought up the possible issue of USB 2.0, I wonder if any of the systems having problems have their AIW and USB sharing IRQ 16? (I know on my gaming machine they do.) One other thing, I haven't upgraded the drivers on that machine in a couple of months. It's running the CAT 5.8s at present. I've tried reading through this thread and likely missed some of the things that were tried. I just wonder, though, if anyone has tried manually installing the WDM drivers (and others) via Device Manager and using the Update Driver option? (In the past, I've had a few times I did have to do that with other AIW cards and different driver updates.) So far, though, this card has not given me a moment's trouble.
