Necro, if you try the new modified rtmpdump
http://www.mediafire.com/?bz3hapxoz5988vl you will be able to download those videos. I've just tried and it is working fine without interruption. So, download new
rtmpdump and copy into
RTMPexplorer folder. Start rtmpexplorer and go to that page. Start video you want to download. rtmpsuck will show you it is downloading the videos.
