No picture only sound

[Mungo Overhill]

I downloaded an avi video but there is only one picture which doesn't move. There is sound.

You most likely don't have the proper video codec, or have an older version of it:

if you see one picture - you probably have the correct codec. Sounds like a divx antifreeze situation.

Not necessarily - if you have, for instance, divx 5.02 installed and the movie has been encoded with 5.05, it might play it for a sec or two and then freeze, also a direct show filter or even an xvid decoder may try to play it but not do a good job of it.

If the right codec is installed then I would guess taking the route of divfix or VDub to check for bad frames. Antifreeze might help, but I would doubt it would fix something freezing that badly.
