system task stuck

[stewart]

HI is there a way to fix this system task Creating video preview images its still at 7903 that seems to be stuck its using 95% of the cpu but the numbers are not changing or if they are they are very slow. I let it over night and its still just sitting there. I tried to stop the task but it does nothing when i restart it is going down very slowly like 1 every 30min to a hour or so way to long
