Just until two weeks ago I was having no problem playing 720p files (be it MKV or MP4) but I don't know what happened, now suddenly I'm having a problem playing those same files. No matter which player I use, the video lags behind the audio or, in the case of VLC, the video constantly freezes for a second or two.
This is definitely not a codec problem as I had K-Lite Codec Pack Full installed for nearly a year and I was able to play everything just fine. Even so, I tried uninstalling that one, and installed CCCP, and there was no difference. I installed CoreAVC, and there is still no difference.
I'm on a Pentium 4, 2.93 GHz processor, with 2 GBRAM, no graphics card, just an Intel Graphics Media Accelerator Driver. All this was working just fine until two weeks ago.
The problem is so severe that I downloaded this video from youtube, it's in FLV format (but encoding is AVC) and even THAT doesn't play properly, either in Media Player ClassicHomecinema or VLC or Splash Lite.
I've checked task manager while playing these files and CPU usage is almost always at 100% or somewhere between 90% - 100% and very rarely does it drop below that.
As for your CPU usage.. That's for another board methinks..
That could be a lot of things though, try killing a few tasks that you don't need running...
