Looks like MTV.ca implemented a new streaming player that makes it harder to find manifest files to download. Not only that, but they also renovated the website and got rid of their earlier content.
I saved a few links, and if I run them with RTMPdump they still download the file so it looks like these files still exist.
Real World London Episode 17:
Code:
rtmpe://cp5290.edgefcs.net/ondemand/mtviestor/_!/mtv.ca/Shows/flv/realworld/S4London/417/RWLondon_417_01
Two things; is there a way to "reverse search" to find more video files, and also, is it still possible to find the highest quality file with these links?
