Unfortunately the problem returns. I’ve got all video on the new HDD. The peak files and program are on the other (old) HDD. Jumping to another part in the source causes delays, not always, but when it does, it takes some five seconds to start playing again. Or moving in the preview window forwards and backwards with the mouse a couple of times will freeze the image for five seconds. In the standard Windows Monitoring I don’t see any big load on the processor (2%) or RAM (3,5GB). If I restart Premiere Pro it goes well fore half an hour or so, then the problems are starting to come back again. Does anyore have any tip where to look at, any help is welcome again.
