I run a subscription-based site for poker training videos. In the recent past, some portion of our subscribers have developed problems downloading our videos. The affected users are exclusively seeing problems while using Chrome as their web browser, however there are other users who use Chrome with no problem.
Here is the exact behavior they are seeing:
- Pasting the url of a video file directly to their browser produces about:blank and the file does not download
- Clicking the link normally produces no result (e.g. it behaves like a dead link)
- Right-clicking the link and opening in a new tab/window produces about:blank and the file does not download
- Right-clicking the link and choosing Save-As produces a 5 to 10 second delay, after which they get a Save As dialog. After they choose a location, the download proceeds at full speed.
Again, this problem has only presented itself for a subset of users browsing with Chrome. All affected users have the latest version of Chrome, but so do some of the unaffected users. All affected users have Windows Vista or Windows XP. As far as we can tell (small sample size), none of the affected users have Windows 7 and none of our users on Windows 7 have been affected.
What could be causing this problem? How could it be solved?
Edit: Here is a copy of the headers from one of these downloads.

Edit: Some updates. Chrome extensions do not seem to affect this. One of the affected systems was upgraded from Windows XP to Windows 7, with no other changes made. That system now downloads properly. This issue doesn't only affect the WMV videos. It happens with FLV and M4V as well.
