Need help for grabbing wmv files from rtsp:// stream

[bshi02]

I use coojah final version to sniff out any rtsp stream while I play online lesson video from online education site.
and soon It found rtsp stream URLs which wrapped with below codes .

rtsp://eduspa.mms.stream.nfractals.com/eduspa/gosi/2009/03/p/ed37ds5gmt/500W8BA11794DS01.wmv?zwoelf&1398436420&refurl=http://www.nambuonline.com/user/cm/crsplay/vod_201304/vodplayer.asp?OpenCrsCode=020120090605O*ApplySeq=0*CrsCode=020120090403M*PlayerType=17*FileType=14*CrsSecNo=0*URLOrder=-1&wms=

rtsp://eduspa.mms.stream.nfractals.com/eduspa/gosi/2009/03/p/ed37ds5gmt/500W8BA11794DS01.wmv?zwoelf&1398437624&refurl=http://www.nambuonline.com/user/cm/crsplay/vod_201304/vodplayer.asp?OpenCrsCode=020120090605O*ApplySeq=0*CrsCode=020120090403M*PlayerType=17*FileType=14*CrsSecNo=0*URLOrder=-1&wms=

FYI,You would notice that there is a difference between two rtsp:// stream URLs.which is digit string of "1398436420" and "1398437624". Coojah captured string of "1398436420" when I have played online lesson video at thirty four minutes past two, while string of "1398437624" was played at fifty four minutes past two.

and I got another information with coojah when I right clicked on these rtsp:// stream URLS then select"COPY whole request header" option

I have tried to Net Transport/ NetXfer to get wmv file from this rtsp stream URLs but It falied to grab any video files.

AS It seems that It is impossbile for myself to succeed to grab any video files from these rtsp:// stream URLs,If there is anyone who is interested in my problem and request reply for link to the video and account, I would sent a private message including account information/ID and PW for geting access to this rtsp:// stream URL.)

I'm sorry for my wierd English and Any reply would be appreciated.Thanks in advance!

I also tried to Replay media catcher5 but It shut itself down as soon as I play/summon online lesson video from this education site.
and
Below log is error message of net transport/Netxfer 2.96 j700 which is shown when I tried to download rtsp stream Urls.
