I currently have a pc to tv converter box so I can watch my computer signal on the TV using the vcr/dvd combo unit. This allows me to record on either tape or disc. How do I do the reverse? Meaning send a TV signal either from the set top box or combo unit INT the computer so I can then PRINT the tv picture either as it is moving or as a still frame from the combo unit? Does it go to one of the folders such as PICTURE of DOCUMENTS? A program such as a scanner, or app such as a word processing program? All of these have a print command. Whatever I see on the screen I can print. It is just a matter of moving the incoming signal to the screen so I can print it. I also have a screen capture program so nothing needs to be saved first. Do I need another box that works in reverse? Connected to a usb port, vga port? Does vga port work in both directions? Details please.
