@ Jiaz

Thanks for your reply ... I really don't know what you mean by "using many connections" , it's the same router , the same internet service provider all the time ..

So, the next link is a playlist of 30 videos, so since JDownloader extracts whatever the link provides I discard the videos themselves and just download the audio files:
**External links are only visible to Support Staff****External links are only visible to Support Staff**

And this is another list of 8 videos which didn't work either but this time I was trying to download the videos themselves and already downloaded them later by Internet Download manager:
**External links are only visible to Support Staff****External links are only visible to Support Staff**

And about the the freezing list issue, it happens only when I move the mouse over any Arabic titles , but it is normal if moved it over any English Titles..

Thank you Jiaz..
