I have a. Mpg in my video section overview inserted in Magix Video Deluxe 16 Special Edition and I can see them error-and smoothly, as long as I s.starte beginning of the video. As soon as I trimmed the video, or a few seconds. will play later, the picture runs faster than the sound.
I've found similar problems in other forums but the solutions are not worked.
I hope you can help me.

This has nothing to do with Magix, your PC is too weak!

Try again the video into formats MAGIX convert and then cut. If that does not work, then I know can not synonymous for hints.
