Single Status Update
Huh. The Xbox One's DVR is the problem, not Magix. Just tested a recording from my new gaming laptop, and that has no problem with skipping frames. If I want to get that Forza video up, I think I might need to record the video as it's playing and see if that helps. And then check the settings on the One's DVR to see if there's other encoding options.
Pretty certain I'll be putting out a new custom song Sonic Generations video within the next two days before that though.
