Please,
I’m out of my mind.
Anything I try to load in VirtualDub (any version) I just get mesage about codec
---------------------------
VirtualDub Error
---------------------------
Couldn’t locate decompressor for format 'DIV3' (Microsoft High-Speed MPEG-4 V3 [Hack: DivX Low-Motion])
VirtualDub requires a Video for Windows (VFW) compatible codec to decompress video. DirectShow codecs, such as those used by Windows Media Player, are not suitable.
---------------------------
OK
---------------------------
I have already instaled bunch of that codecs and always same old story.
Sory about english.
Thanks 
That’s the divx 3 codec. Get it here

You’ll get another popup from virtualdub, but you can ignore it. To read the whole story go here
