I cannot use Capture at all -- on either a DVD movie or on streaming video. Just loading the program makes the video and audio slow and jerky, and this is what's recorded. I've tried all combos of setting for both audio and video, played with my video card acceleration. The setup tests went fine, and I have no problem using WM Recorder. Any suggestions?

XP Pro, SP3, 4GB memory, NVidia GeForce 7900GS, V. 178.24, RealTek audio.

Thanks in advance.
