Personnelly i prefer to use vdownloader to download any videos from youtube. It is simple in term of using it and robust too. However lately i encounter a problem to download video from youtube. Alternatively i use another simple software to do the job for me. It is youtubedownloader. Here is the step to use this software.
1. Copy Video’s URL to space given as below.
2. After downloaded completed, you may proceed with step 2 as below.
That it. Simple right?
