I've just downloaded both zips (rtmpdump-2.4.zip from mediafire, from first post and RTMPDumpHelper from Nir Sofer's site). Extracted them in new folder (both in one). BTW, rtmpsuck's MD5 equals to yours.
Then I start rtmpdumphelper from that folder (it starts the rtmpsuck) and open the same test page (
http://live.samaa.tv/). RTMPSuck starts capturing the stream, but saves it as samaalive.flv, without timestamp
I cannot understand it.
Everybody, please, test that issue too. It can't be that i'm the only lucky who experiences the overwriting problem.
