I used to have the divx 5.0 codec installed, encoded some video clips and played them just fine.
I upgraded to divx 5.1 to play some movies that required it (downloaded clips). I tried to go back down to 5.0 by uninstalling and now I have 2 issues. These issues are not resolved even when going back up to 5.1.
1) Windows Media Player 6.4 or 9 no longer plays any divx AVIs. It says it's an unsupported format. Divx Player will play them fine, however. How do I get WMP6.4 to do it again?
2) VirtualDub doesn't show DIVX as a compression option any longer. Tried reinstalling 5.0/5.1/5.11 but none of them show up. How do I get VirtualDub to realize there's a divx encoder installed ? EDIT>>> Fixed:
