Hi and welcome
I might need to know a bit more about the symptoms (how often are the jumps? All through the footage at 2-3 second intervals or just occasionally?)
Have you tried to open the footage in Quicktime to narrow down the problem to Final Cut Pro?
Can I ask where you are capturing to? Is it an external or an internal drive? If it's external how is that drive connected?
Its also possible that the short segments of recording that you are missing are over sreas of "spanned" media. You might want to check out THIS ARTICLE.
I'll keep an eye on this thread.
Cheers
