Since the Youtube TOS doesn't allow downloading (unless there is a download button) we don't help with such issues.

I have downloaded real player to be able to dowload videos from websites especially from youtube. Unfortunately each time I try to download a video it stops half way. I have tried this on several videos but its same. Then I tried youtube downloader and here too its the same thing. Can anyone help me with this issue? Thanks
