"Recover"/Convert/Download Local Silverlight files to video

[enzeru]

There's a video service that offers a particular program (executable) to download videos from their streaming site and watch them offline, however it seems that there's little to no information about this.

This program is apparently using Silverlight since making a right click anywhere on the interface will trigger a "Silverlight" option. This is the link to the program in case somebody wants to check it: https://www.clarovideo.com/fe/sitesplus/sk_telmex/swf/CentrodeDescarga.msi

Now, the files are stored in folders called "audio", "video", "clientmanifest", and inside them there are multiple *.audio and *.video files which I believe is a single file divided for "security reasons".

This is an example of all of these files, it's a 23 minute video: https://mega.nz/#!BdVHDDiJ!J5wrjq7xzRWvP1d7P-Kw49cqbaysiYYSEq3FVF8IHRM

Now if there is a way to merge all these files into a single video and audio file, I think that would be the easier option. The second one would be finding a way to make this program export the merged video file.

Any help would be greatly appreciated.

How do you watch the downloaded video offline? Does the software include a player?

[enzeru]

Yes, the software is actually a downloader and a video player which works under Siverlight as I said before. The video files are stored in my computer locally. You can check one of these videos in the zip file of the first post.

I noticed at the end of the manifest file there's:

Which is probably a decryption key. But without knowing the exact algorithm you won't be able to use it.

[enzeru]

Oh, so there's no way to decrypt them or convert it to a single video file?

[jagabo]

I don't know of a way. But I'm certainly no expert on the matter.
