Video Capture aborted due to doppes frames

[abx992000]

I have a few problems, and I don´t find any solution. Maybe somebody has an idea:

I capture Movie through Mojo and I have to capture for example 45 min. If I stop the recording, the audio is completely recorded, the video is sometimes 35 min, sometimes 24 min... recorded and the alert appears: Video Capture aborted due to dropped frames. No workaround fixed this problem (only video recording, sessions with no plugins and only 2 audio tracks...) Sometimes it works but most of the time the video is corrupt.

Thank you for every help!
