Tested NetTransport (NetXFer) 2.96b. It allows to download RTMPE streams. But I wasn't able to find any RTMPE URLs with its URL Sniffer. The program doesn't have any additional fields for SWF verification as well as many other RTMPE parameters, but I was able to download RTMPE streaming videos from MTV, Crunchyroll, vpro.nl using it.
