сам нашел решение!!! :punk: Рассказываю, может кому-нибудь пригодится :)
If you have installed the DivX codec on your Windows system yet find it does not appear in the list of video compressors in applications such as VirtualDub and the like, then you should follow these steps very carefully.
From the Start menu choose Run and enter:
RegEdit
Browse to this registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
Look for any entry which has no data associated with it, other than the "(Default)" entry. Remove any such entries.
Note: Before editing you should export this key to file as a backup. To do so choose Export from the File menu.
Once you have done this, close RegEdit
Using Explorer browse to your Windows folder (by default C:\Windows) and open the file System.ini.
The System.ini file is divided into several sections seperated by headings like this:
[Heading]
Locate the [Drivers32] section, and as before remove any entries with no data assigned. For example:
vidc.DIVX=
is an entry with no data assigned because there is nothing following the equals sign.
Restart your computer.
If DivX is still unavailable as a compressor following these steps then the DivX encoder may not support the colorspace of your source video.
