I'm a registered user at Digital Tutors. Due to not having so much of a good connection I would like to save videos for offline viewing and learning.

Steps I have tried:

1.Downloading the streams using IDM but I'm unable to play the flv as it's somehow corrupted.

2.I tried rtmpExplorer but when I'm logged out and download the free videos, they download completely and I'm able to play them without any problem. It's only when I'm logged in it just doesn't catch up the download and sits there idle.
