First i tried with youtube-dl and all the times ( and all days) for all videos it gives this same error:
youtube-dl http://www.youtube.com/watch?v=6zWwTTAc7O8 [youtube] Setting language [youtube] 6zWwTTAc7O8: Downloading video info webpage [youtube] 6zWwTTAc7O8: Extracting video information ERROR: format not available for video
Then I tried minitube latest version. but it just cant open the video. it just keeps trying to open video. it is unable to even play or download any video.
Also in old days, whenever i play video in youtube.com that was automatically was saved in my /tmp. But that is also not happening these days.
What can I use for downloading Youtube videos? I am using Lucid 64 bit.
Edit1: I dont want to use any extensions to Firefox. I like my firefox without any extension. With extension it becomes soooooo slow and inactive.
