Hi. I just bought a 1TB transcend external HDD storejet. i used it to play movie directly through my lappie. I noticed there's some random freeze/stutter/jerk when I play mkv movies through media player classic with latest codecs. I tested with VLC too still encountered some random stutter. WHen it happens, the computer doesnt hang, just the video seems to stuck while audio jerks a little and Media player hangs a bit, after a few secs it will return to normal state and continue playing. or i have to slide forward or reverse then it will be normal again. No fixed time it will occur,  and i have been trying to look online and havent found any working solutions.

i have done defrag, updated my drivers, updated my codecs, used other players (VLC seems to play better but still stuck a lil tho less frequent), rebooted, bla bla. I will try to copy the movie and play directly using the internal drives and see how. anyone have encountered this before or please shed some lights as it has been quite frustrating as i doubt the lappie is underpowered. It is lenovo Y510p gaming series and the hardware should be sufficient plus the media is played thru USB 3.0.

thanks sifus!
