Description

There are some more points to this issue:

• This is not always the case, for example the following URLs WILL download: https://www.veoh.com/watch/v1313193ABWGBcdJ, https://www.veoh.com/watch/v1313969NS4A9N6p
• Also note that on the above "working" examples, the website reports filesizes around ~= 250MB while the downloaded files will be around ~=70 MB.
