I am having problems playing 1080p mp4 videos on my computer, and I can't figure out what the cause might be. This is my machine:
OS: Vista x64
CPU: AMD Phenom II X2 - 3.1 GHz Dual Core
Video Card: HD 5770 - 1GB
Memory: 8GB RAM
Disk Drive: Western Digital - 2TB w/ 64MB Cache - SATA 3.0 Gb/s
...WHAT I HAVE TRIED SO FAR...
FIRST TRY: When I first tried playing the video, I was playing it on Windows Media Player (latest version, no updates available) using the K Lite Codec pack. The video had some visual artifacting and it kept lagging and skipping (audio seemed to play forward at a regular speed while the video played back in a disjointed and slow manner). Looking at system performance in task manager showed that the CPU was pegging, with Windows Media Player using up as much of the CPU as it could (the rest being used by other open apps, of which there were only a few). Memory usage wasn't very high, but the CPU was bouncing around between 80% and 90+% usage. Even after I tried closing the other apps, the playback remained the same.
SECOND TRY: I uninstalled K Lite and installed VLC. This was worse. The CPU pegged and the video basically froze, playing back audio but only intermittent, broken pictures that looked like negatives.
THIRD TRY: I uninstalled VLC and installed DivX. Same as VLC.
FOURTH TRY: I uninstalled DivX and installed haali media splitter and ffdshow. Then I tried running it in Windows Media Player again (since that was the player that gave me the best performance so far). It seemed to be the same as the first attempt: minor visual artifacting with slow and jerky playback.
I would think my machine would be enough to run 1080p videos, but something is clearly not working right. Does anyone have any suggestions? Thanks!
