Sounds like a software problem rather than a problem with the clips themselves. I'd try playing the clips in with something else. If they play OK with a different application (clip browser?) or on a different computer then it will be an issue with your software or operating system.

Is your system overclocked? That could be a reason for corrupted transfers as Windows copies what it can and caches it in memory. If the memory is corrupting the data, that could be a reason.

Also, ensure your HDDs are getting proper ventilation. Overheating HDDs corrupt data as well.

TL; DR, if there's an overclock on your system, immediately go back to stock speeds.

Thanks for the help, i check it en contact my cpu builder

the problem was 1 of the 4 memory cards in the PC, i have 16gb of memory (on 4 cards). I did a test to copy the clips with every time 1 x 4gb and with 1 card i have errors in the clips, then i did a memory test on that card and ther also i get errors, so problem solved! Thanks for the info!!
