M'kay, so I've been seeing some posts saying that people don't
understand how to download from DownThisVideo, so I'll take this a
step at a time. First off, the home page. Simple enough. Enter the URL
of the desired video, example :http://www.youtube.com/watch?
v=a7FQPMiph9M.
This will take you to another page showing the information of the
video. Here's the part where most people get confused. At the bottom,
a button saying "Download FLV" should appear. RIGHT-CLICK and select
'save target as...'. This will open a download window. Under file
name, save it as you like and add a .flv at the end of it.
example: Robots.flv <---- don't forget to add that .flv or else the
file won't open properly!
Under 'Save as Type', select 'All Files', choose the location of your
file and save. And voila, an flv file downloaded into your computer.
But that's not the end of it, you'll need an FLV player to play the
files (if your computer doesn't already support it). You can easily
google these and find them. If you want to convert .flv files you'll
need an FLV converter (again, you can google these). Keep in mind that
most converters are not free and those that are usually not very high
quality.
Hope this helps!
