Question changing video format and a blinking screen

Hi Everybody-

I am taking video from a VHS-C tape and converting it to DVD for a friend, my issues is that while the video plays and records on my PC, the screen of the playback blinks in and out with a black screen, the sound is fine, but the video keeps going in and out, I use tracking to try to remedy it, but it doesn't totally fix it, and another funny thing is that one part of the tape will do this blinking, but other parts of the same tape on the same playback will be perfectly fine.

If anybody can help explain what might cause this, i.e., different recording settings, playback issues etc. would be wonderful.

Thanks in advance- Douglas
