Gabby is trying to digitize video tapes with her computer, but it won't play on the laptop with her capture software. What Leo suspects is the the device isn't seeing her VCR. She may also need to look in the VCR's menu settings to see if it has the right output settings. The TV she has connected is probably causing a handshake issue, so it's advised to disconnect it from the equation.
