I just installed WinXP. Then I installed the divx3.11 codec and then the divx4.12 codec and answered no when it asks if you want divx4.12 to play all divx3.11 content. This is what I did when I had win2000 and I could watch every *.avi files. Now, some files are fine, but some I only hear sound no picture. Anyone know how I can fix this? I know the files aren't corrupt or anything cuz I was able to watch them when I had win2k. Any comments or suggestions will be greatly appreciated. Thanks in advance.
