Geforce4 TI-4200 White box while capturing

[jwilson56]

I have been trying to get this Evga Geforce TI-4200 to capture some home video's. I can see the picture fine in preview but no matter what I try I get a white horizontal box across the picture on playback. I have tried Virtualdub as well as a couple other capture programs and they all come out the same. I have tried the 1.11, 1.12 and 1.16 VIVO drivers. Any ideas as to what could be wrong? Thanks

I get the same thing using a Prolink Ti4200, but it's only if the source video is garbled. Like if I pause the VCR, or FF/Rewind.

If the source video is clear, the box goes away. Using Nvidia 1.16 WDM capture drivers, and composite in. So, I dunno. Hopefully a video capture guru will speak up, I'm new to this whole thing.

i suspect - without seeing it - that the vcr or your source is not exactly putting out 29.97 (or 25 if you are PAL) .. this is a problem with a lot of vcrs's and really in fact it dosnt ussually mater as your tv dosnt care ... but some capture cards do ... and dont work to well when the frame ratre is slightly off .. hence the need for time base correctors ..

there are other causes for this -- but what you describe sounds like time error tearing.

Any suggestions as to some type of black box to use in front of the video input to clean up the signal to prevent this?

Thanks for the replies.

Well I tried my camcorder direct and it captures fine. Wow all the hours spent only to find the answer here. Great job guys. Too bad the Evga support techs weren't as good.
