Sound gets delayed and video is shaky in WIndows Media Player

Hi.
I notice two problems that happen when using windows media player. Ocassionally if I’m viewing an avi file.. it will play normally but the sound and video gets out of synsc. I know the video and sounds are probably synced when I view the same exact file on another computer. Also, occasionally some avi files appear shaky when playing in windows media.. but are fine when I use something else. Does anyone know what I need to do to fix the problem? I’m assuming I’m just missing a codec but not sure which? Please if anyone can help me.

Download VLC player from www.download.com

Out of sync audio and “shaky” video has usually one of two causes:
1. Bad encoding in the source. This is unlikely since you’re able to play the file correctly on another computer.
2. Underpowered CPU. Videos encoded in some codecs are extremely processor-intensive. If your CPU is not powerful enough you’ll get dropped frames, out-of-sync audio, and occasional freezes. An easy way to check in Windows NT and later (2000 XP Vista) is to right click the taskbar and pick task manager, and during playback of the video look under the performance tab. If it’s at 100% CPU usage then your CPU is underpowered. There’s not much you can do besides get newer hardware. You can however allocate as much processor power to video playback as possible by closing all other programs and background processes and unused stuff in the system tray. Also if the video is in DivX and you’re using the DivX codec you can try turning off post-processing in the settings.

anonymous,

I am also having the problem described. I have loooked to see if it is an underpowered CPU problem, and it appears that it is. I just wanted to know if it is just the play back of the videos that is the problem or is it the actual downloaded file? ie. If I did manage to improve my CPU’s performance, would the file play with audio and video in sync?

It’s neither really the video nor the CPU (and it’s kind of both at the same time too). It’s the decoder. You would indeed need a more powerful CPU to play things in sync. (An increase of just a few hundred MHz in clock speed may not do the trick - it usually takes moving up to the following generation of CPU’s)

I have a similar problem as stated above. I have a video edited on a computer then put onto a disc. Both the file and the file on the disc play fine when played on the original computer but if I move the disc to another computer, the sound and video are very choppy.
I checked my CPU usage and it was around 25%, not really sure what I should do but this is an urgent problem and I would appreciate any help I can get.

I am getting the same thing. I packed up my computer for 9 months while away and have come back to add and edit videos and this is happening. CPU usage is about 17%. The only thing I have done since getting it back out of the box is updating Virus software but surely it can’t be this. Help anyone please
