Windows Forum / Windows Media / Player / April 2008Jerky playback
I have a wmv file that has played just fine for over a year. I use it in a powerpoint presentation. Suddenly it started playing jerky - the audio is fine but the video starts and stops at random. First, the environment: a. XP Professional, SP2 b. Nothing else running on the system per the task manager. c. On task manager, media player shows between 45 and 60 % CPU while playing the movie. d. Running Norton 360. I upgraded to WMP 11 - didn't help. I thought maybe the file was corrupted so I renamed the old file and made a fresh copy from another computer. Didn't help. I noticed that if I play the movie a second time (replay) it isn't jerky... it's only jerky the first time that I play it. I then discovered that all of my clips are the same - jerky the first time but not the second time. AHA! A buffering problem! I enlarged the read-ahead buffer to 20 seconds. Didn't help. I'm stumped. What could have changed, even by mistake, that could be causing this? Could Windows Update have changed something on me? Or a Norton update? Do you still need help with this?

I have tried using the PowerPoint Viewer, but the playback is still jerky, although the buffering thing still seems to fix the problem. That doesn't help me, though, because I can't buffer the video during my presentation. > Do you still need help with this? > [quoted text clipped - 29 lines] > > What could have changed, even by mistake, that could be causing this?

Anyway, *perhaps* the cause is the same as I had (also on XP Professional, SP1 or 2 (I don't remember)), lack of System cache for buffering. Try this: Control Panel -> System -> Advanced -> Performance -> Settings -> Advanced -> Memory usage. If it is set to "Programs", change it to "System cache". If I remember correctly, you have to reboot to make the change effective. I hope this helps. > Yes, I do! > [quoted text clipped - 36 lines] > > > this?

I also tried disabling Norton 360... that didn't help either. > Do you still need help with this? > [quoted text clipped - 29 lines] > > What could have changed, even by mistake, that could be causing this?
