Capturing VCR blue screen and dropping frame!??!

[Pitou]

Hello,

My system is a P4 1.7mhz with a dedicated 80 gigs 7200 8mb cache WDC to capture.

I'm using Win XP with virtualVCR. I'm dropping consecutive frames after about 55 mins of capture. It's not some frames here and there, it's like a bunch of frames at the same time.

Now I'm capturing the vcr blue screen, so no tapes in the vcr and I'm still dropping frames after about 55 mins.

I deactivated all services in XP, all background tasks, no difference.

I really don't know what's happening, any idea??

Thanks

Pitou.

When I set my resolution too high, the same happens to me. What settings are you trying to capture at?

Hello,

I capture at 720x480 30 fps with a BT848 chip. I'm using Huffyuv as the codec but I also tried MJPEG with a very low quality so minimize the transfer rate, no luck.

Please take note that it was working before. I had to reformat for some reason.

Also, this happens about every hour. So I loose frames at 100000 frames, at 200000 frames, etc.....

I sat down in front on my PC and everytime it looses frames at bout every hour, I can see the HD LED become solid RED for about a second. So that's why I suspect the HD of the OS.

I'm going to try Win2000 instead of XP

Thanks for taking time to help me.

try turning off cache write behind before capture

[Pitou]

I tried turning cache write off, in the device manager of XP.

But then I get a lot of frames drop all over the place.

btw, I use Virtual VCR since I want a WDM capture software
