With so much potential yet to fail in execution. Purchased online. Not a pirated copy. XP Quad Core system, 8800gtx, 4gb DDR2, etc... problem, with Nero 7 and trying to edit AVCHD files the computer would always lock up when adding titles, effects,etc.... So, I wait and now an update is available which cured that problem. But now the video is choppy. The video sort of gets jerky all over the place. No more hangups but now the annoying jerkiness. I completely deleted it through the registry as well and reinstalled. Same problem. Installed on another computer. Same problem. Any ideas? Latest drivers on everything, no change. thanks in advance.
