After I capture my video the sound and video will be off by 2 to 10 seconds. During capture it appears to be fine. I am using a pci capture card and have a 40 gig main drive on ide and 160 gig on raid for the capture. I am running a P4 2.8 intel with 800mhz front side bus. I am running 1 gig of 400mhz ddr dual channel ram. The video card is an nvidia run of the mill card, nothing fancy. Before I built this machine I had it in a p4 2.4 533 fsb machine and it did the same thing. Am I doing something wrong here? Is raid doing it? I would be thankfull for any help in this matter.
4 questions: Is the Nvidia card capable of locking the audio? What file format/codec are you capturing to? Try changing this. Is the audio off by the same interval all the time, or does it get progressively worse/better? Which plays first, video or audio?

Most Sync Problem durring Capture are Due to the fact that the Video Capture and the audio capture are running on 2 seperate Time Clocks..So you need Capture software that can compensate for the Different Time clocks, or you need a Capture device that Locks the audio and Video streams so they are both being Captured useing the same Time Clock...Haveing a High Quality sound Card can also help with the drifting audio...Some Capture Softwares that are good at compensateing for the Different Time clocks are IU_VCR for AVI capture and WinDVR 3.0 for Mpeg capture...Your capture software might allready have an option for keeping sync, it might have a setting like "Master Stream" which should usually be set to "Audio" for the best Sync, especially if you are Planning to make a (S)VCD or DVD out of the Capture....Cheers
