I have recently upgraded from BX/Pentium III 833EB to A7V133/Athlon 1.3 GHz motherboard. All other components remained the same. I am having problems (video noise) when capturing video from Canon camcorder. Specks 2x5 or so pixels in three to five frames in each 2 minute clip. Here are few samples http://members.home.net/witekm/dv_capture.htm.

I have tried MSP6.0, Scenalyzer, Windows Movie Maker and small aplet from ADS http://www.adstech.com/products/PYRO1394DV/downloads/applications/wmcap.exe. Results are the same under both WinSE and WinXP Pro. No shared IRQ's. Disk performance as reported by VDub 1.4: Sustained read 19469 K/s, Sustained write 19574 K/s

There are a number of comments I'd make.

The first is that a LOT of people around here do not get satisfactory results with Windows ME and have either reverted to 98SE or upgraded to 2000. You're saying you've tried Movie Maker, so I guess you are running ME.

Next, it is vital when upgrading a motherboard to install the correct motherboard drivers - these will have been provided on a CD with the motherboard, but you should also check to see if there are later drivers available from the motherboard maker's web site.

If you abandon ME and move to 98SE or 2000, then you must install the latest version of DirectX - DirectX8a - and the DirectX 8 DV updater.

I'm not sure whether or not this is also the case for ME, but I don't think that installing them could do anything but good.

Finally, it is possible that the FireWire cable or one of the FireWire sockets is iffy - so do try a known good FireWire cable if possible.

Bob,

I run WindowsSE with all DirectX patches and WindowsXP with DirectX 8.1. Problem is present in both.

I istalled my Pyro card in friends machine (P3/500). No problems, no glitches.

Using MSP6.0 on my machine I generated pure software DV Type1 file. There is no cables, cameras, capture cards involved. Here is result: http://members.home.net/witekm/DVglitch.htm
