no picture on a video clip

[KnickKnack]

I have a few movie clips of the kids, one in particular I would hate to lose.
They were taken via a webcam, they are .avi files.
I normally play them on VLC.

They usually play just fine...but not today,
The sound if fine, but there is no picture

any ideas?

I just downloaded an updated version of VLC.

When I tried to play the movie clip this error message appeared (still has sound but no picture):

No suitable decoder module:
VLC does not support the audio or video format "IV50". Unfortunately there is no way for you to fix this

Some answers here

I've already tried the codec option...that didn't work.

I'll give GOMplayer a go, and if that doesn't work I'll look at the other suggestions

thanks

well whadaya know, Gomplayer worked

happy days
