First I tried versiontracker and softpaedia - usually good sources for utilities (that’s where accidentally I found blender!). But they only had the pro codec.
My googles (I think I was looking for “divx coded os x”) turned up all sorts of useless links. One “free download centre” had me click through 3 different pages and at the end it offered me an .exe file to download - for a Mac!!! It was from there that I navigated back to Divx’s home page (I’d been there before but must have ended up on the DivxPro page instead of the free download page)
Here’s what the licence agreement says:
BANNERS: This sooftware will download banners from our servers and display them within the GUI of the software. A message will be sent from the software to our servers indicating that an ad has been served. etc…
SOFTWARE INSTALLATION: When the software is installed an installation ID will be sent to our servers. This installation ID will be used only to track installs compared to downloads and will not be prsonally identifiable.
I don’t usually read these agreements but for some reason I read this one. Maybe I’m just being paranoid. But I wonder what happens if you don’t have net access on the user’s computer?
