Hi Everyone,,,
Before Saying Anything, I'd like to Thank all of you guys for your Amazing,Helpful answers .
I'm so grateful for every single word I Learned from this great community
I'm facing a real problem this time in downloading from this website .
Like I said in my question, the website is working by the "Microsoft Smooth Streaming" Platform,
The whole thing I think, moves around the 'ism' & 'manifest' page/file, and fortunately, both of them are reachable directly .
After long search and many trials, I was successfully able to download videos, by constructing some Direct URLs (using ism file) for different video qualities.
But the bad news is, the videos were decrypted by "PlayReady DRM"

!!
Again, I've came to an end, and I really don't know what to do next
I've made a text file of all the needed info in case of, some expert decided to help.
Thank You guys for your time,
and I Really wish If anyone can help .
