One of the technical notes on the Dazzle site says that DV.now performance may suffer from IRQ sharing. Windows 2000 tends to use IRQ 9 for all bandwidth hungry devices (such as video card, sound card, scsi controller) including the DV.now AV card. Now, the Microsoft Knowlede Base says that the only way around this is to install Windows 2000 with the "Standard PC" HAL (hardware abstraction layer) instead of the default "ACPI" HAL.
Has anybody here ever successfully installed Windows 2000 with a non-ACPI HAL? I've tried this "Standard PC" setting two times, but my computer failed to boot up (disk read error) after Windows Setup was done. I wonder if it's worth to keep trying.
Have you tried W2K with the IRQ sharing? On my system running W2K with most things sharing IRQ9 with DV.now AV seems to work OK.
Yes, it works OK most of the time. I was just thinking that I might be able to squeeze out a bit more performance by disabling the IRQ sharing, and I needed to reinstall Windows anyways.
None of the problems I have are fatal, more like annoying (such as jerky playback in the FAST.forward video window during capture). Running PIII 733MHz with a GF2 MX video card by the way.
I'd appreciate if someone with experience in this could enlighten me if it's doable and if it's worth doing.
Unless you have a big problem it is not worth it. I tried it once and nothing better happened.
Then I returned to ACPI mode again.
I install positively Win2000 few times, but it is worth only if you have old cards like AV Master which is not working with ACPI.
hard cut
thonderson, May i suggest trying(each time you begin a new project-or at least once a month) defragmenting both your system drive and capture drive before you start. This can ensure smooth access to captured files and program files. BTW are all you drives 7,200 rpm or a mix of 5,400 and 7,200? Others have had trouble mixing these. ALso the windoze defragmenter is really slow, so I'd get a better one from a 3rd party software company.
