When I play 1080p video and there is lot of disk activity at the same time (virus database updates, someone copys something trough local network, DVD is burning...anyway - lot of hard disk activity) then the video shows very poor peformence - stops and starts for sec, then stops, slideshows and so on (allso with sound). When this happens the CPU is about 50-60% so CPU is not an issue. I allso set the media player priority to high in task manager - still bad peformence when hard drive activity is high.
I have AMD CPU 3GHz, 3,5MB RAM, 1GB ATI Radeion HD4850
I DID NOT HAVE ANY SUCH ISSUE ON XP...whats the problem?
