color changes during capture

i notice that whenever i try to capture fom any source, there are color shifts, usuaaly above the frames.it changes from the usual skin tone to yellow and somtimes magenta. i even changed to a high quality cable (quantum video cable) but still it still persist. im using leadtek dv200xp and its pvr.
how can i solve this?

 

What are you captureing , TV or VHS??

 

im capturin analog source, vhs, v8, beta. on tv its ok. as if it is copyprotected just like macrovision. it changes in color. but they are home videos?

 

That is why I asked because Macrovision Causes the Video to go dark and bright on Protected VHS tapes but if these are Hove Movies then it couldn"t be Macrovision but I don"t know what it could be....
Maybe try different Capture software and/or a different VCR and see if you have any Luck.....Sorry I can"t help Much...Cheers

 

thanks for the help..i really can't fgure out why.. before i suspected my wireles keyboard and mouse might be sending rf signals, and i even changed my video cable to quantum ...ohh well...
