I can't imagine your reasoning. But putting media in device memory doesn't make sense to me, especially videos which generally would tend to be larger files.
That said, what you are observing is a symptom of boogered .dat files, and is typically corrected by deleting the .dat files and letting the device recreate.
Regardless, I recommend using the media card for your videos as well as other media files.
