Problem with Audio/Video timing while playing video?

I recently uploaded a video on youtube in mpg format. the video at my hard disk is not compressed and is in VCD quality. there is no problem with audio and video synchronization while playing at my hard disk.

but when i m playing this video on youtube, there is much difference in audio and video timing. and all the parts of this video (about 31 parts) having the same problem. i never get this problem before videos that i have uploaded.
kindly have a look at the video link and please suggest me what is the problem ?
and how can i solve this ?
