google chrome - Download MP4 file instead of playing it using ChromeDriver?

Question

I'm using Chrome Web Driver 2.10 chromedriver_win32.zip with Selenium WebDriver 2.31.2.

With verbose logging enabled it seems the DesiredCapabilities (https://sites.google.com/a/chromium.org/chromedriver/capabilities) are passed just fine,

[1.174][FINE]:      Initializing session with capabilities {

   "browserName": "chrome",

   "chrome.switches": [  ],

   "chromeOptions": {

      "args": [  ],

      "binary": "",

      "extensions": [  ],

      "prefs": {

         "download.default_directory": "C:\Downloads",

         "download.directory_upgrade": "true",

         "download.extensions_to_open": "",

         "download.prompt_for_download": "false"

      }

   },

   "javascriptEnabled": true,

   "platform": "WINDOWS",

   "version": ""

}

but Chrome Web Driver is playing *.mp4 instead of downloading.

I've tried the solution at How to set Chrome preferences using Selenium Webdriver .NET binding? but it doesn't seem to work with newer Chrome Web Driver version, and it crashes if i try and use selenium-dotnet-2.31.2 with chromedriver_win_26.0.1383.0.

Anybody has a suggestion?

ChromeOptions options = new ChromeOptions();
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("profile.default_content_settings.popups", 0);
prefs.put("download.default_directory", getClass().getResource("/data/input").toString().replace("%20", " ").replace("file:","").replaceFirst("/", ""));
options.setExperimentalOption("prefs", prefs);

options.addArguments("--test-type");
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
