Find hidden VODs on Twitch.tv ?

[torchi12]

There is a channel (Twitch) that somehow automatically hides their VODs(some deal with Twitch?) and it never shows up under past broadcast but the vods do exist. The URLs to the VODs are in the format of http://www.twitch.tv/<channel>/b/<a long number like 557397787> I found that number for one of the VODs and was able to download it.

Is there any way to get these <long number>s? VOD ids or whatever they are.

After I got the vod ID I used (http://api.justin.tv/api/broadcast/b...551240062.json) to get info and links to the downloads (that id doesn't seem to work anymore, probably deleted as it was a while ago).
Here's the info I got, might be able to use it somehow to find out other hidden vods(in the future): [{"broadcast_id":10401902448,"id":551231439,"length":1800,"start_time":"2014-07- - Pastebin.com
I use JSON Editor Online - view, edit and format JSON online to make it readable.
