When I play this Xvid video clip ( .avi file ; From Gspot, I discovered it is a Xvid video with mp3 audio) it keeps on "stuttering" the whole time ! I used Xvid 2.1 and BSPlayer : nothing changed with the stuttering . I tried VirtualDub v1.6.3 but it could not even play the video . The error message was that it could not find an audio decompressor to process the audio ! I even loaded the "AC-3 ACM Decompressor 0.7" and Lame mp3 decoder but it still did not work . Is there a chance to fix this audio problem ? Please comment.
