Hi Tamara,

The files which are causing issues have the same format as the previously used videos ?
Was there any different media framework selected in Preferences of ELAN for these videos ? If not then, as you have stored the files on your hard drive and still face the problem, one of the reason could be high quality videos. High quality videos can be demanding on the system especially if the codec is not optimised.
We advise to look into the video encoding of these files.
Try re-encoding your videos to a form as suggested here to a ELAN-friendly format.
