I was having some troubles with Windows Explorer crashing – explorer.exe errors – when I was trying to either move DivX or Xvid files around on my computer or watch them. After a quick Google it turns out that it’s actually a problem with these codecs and SP2 for Windows. The latest version of DivX fixes this problem for both DivX and Xvid files. You can get the codec here. When it’s installing, it will ask you if you want a free trial of DivX Pro – no need to do this if all you want to do is playback files. I would also recommend using Media Player Classic as your default player which can be found here (scroll down until you see the file) or from the links on my Files page.
