There are several ways to hook a vcr up to a PC monitor, but most of them depend on the outputs of the vcr and inputs and other features of the monitor. The easiest and usually cheapest way is to buy a tv tuner for your PC. These tuners cost from $20-$200. Another way is to use a vga box which will de-interlace the vcr input and upscale the rez for the monitor. If your vcr has rca component out and the moniter supports sync on green then you could use a straight through component to vga adapter. Also some older monitors as well as fairly expensive new ones may have some type of rca or s-video input.
