you're gonna get lag trying to play off the PC monitor. that is given. however, the amount of lag is dependant on numerous factors. as it is, the amount of lag I get (using a VideoAdvantageUSB capture box) varies from milliseconds (enough to throw my timing off) to a full second.
the ideal solution is, like stated above, to split the signals (at the very least the video signal). if you can't, you're gonna have to deal with it. |
