Video Tutorial How to use SaveTube to BackUp your YouTube and Google Videos
It looks like some of you report having 2 common problems.
Common Problem 1: No download link when I paste the video address in.
-Be sure to paste in the Video URL in the right format. See the example near the Help button. You will have to cut off things like "&feature=bz301" that might come with the copied URL address, if any present.
-It might be possible that the video you are trying to download was removed from youtube and is not accessible anymore.
-You are maybe using a browser that doesn't have support for this service. Try using the latest Firefox or Internet Explorer.
-You might not have Javascript Enabled on your browser, or your Security Settings are too high.
-The SaveTube server is too busy, sometimes there are 100 people trying to backup at the same time. Be patient, click GO and wait for your turn.
Common Problem 2: I don't know what to do with the get_video file that I got from SaveTube
When the download is finished, just rename the file from get_video to somevideo.flv ... Just add a .flv extension, then use an FLV Player to play it. You can also convert it. Go to the tools page for more info.
Common FLV extension problem / If opens in MS-DOS
Some users report not seeing file name extensions or having their get_video open in MS DOS. Don't worry! This happens because Windows doesn't find an extension of the file so it automatically reads it with MS DOS. You will have to rename the file, but if you don't see extensions, just follow these steps.
