Hi,

I am using iuVCR to capture s-video input, using my TV-PCB05 (http://www.amazon.com/Sabrent-TV-PCB05-Capture-PCMCIA-Cardbus/dp/B000B5KNWE) card (SAA7134). I am capturing at 640x480, 29.97fps, YUY2, HuffYUV 2.1.1 CCESP Patch v0.2.5.

The captured video has these horizontal line artifacts, always in sort of the same area. See below (click for more.. I've also attached them):

This doesn't seem to happen when I capture at 320x480 YUY2.. but it does happen at 320x480 RGB24.

I tried using VirtualVCR but I get the same artifacts.

I've also tried disabling compression, and the artifacts are still there. I've tried capturing the composite instead of s-video, and I get the same thing.

I'm running WinXP SP3.. Core 2 Duo T7300, 4GB RAM.

I use the same card on my older laptop using the same settings without this problem.

Anyone have any ideas? Not sure where to begin with debugging.
