Okay, so I've gotten a new Video Amp from Ultimarc and the picture is much stableler (is that a word? 

) and I've even configured powerstrip 640x280 so now everything, from boot up to any game I decide to load, flips at the same slow rate.  Hence lies the problem.....I get close, but I still cannot get a solid V-Hold lock at all, no matter how much I fiddle with the monitor's external control panel.  Is there anyway to bypass the monitor's v-hold pot and "software lock" it?  I know on computer monitors, V-Hold isn't an issue, regardless of the game.
I'm running ArcadeVga->Video Amp->Sharp Image 33" Arcade Monitor.
Please HELP!
