Missing arguments?

[AltairAC]

I am a member of a video web site which requires payment for access. It provides streams via flowplayer and the format of the videos is FLV. I had no problems downloading the videos with a Firefox addon called NetVideoHunter but today they started to use the rtmpe protocol which is a problem. I analyzed the html code and according to that, I made a rtmpdump command:

rtmpdump -r "rtmpe://5.9.30.50:1935/vod/13800503074ba43.flv" -T "#kuca#voli@macu159#753" -o 1.flv

I got the video url via StreamTransport, I found the token in the html code. The downloaded Video works but it's strange, it's 3.4GB in size but it should be around 500-600MB. I tried to re-encode the video with ffmpeg, while re-encoding I get a bunch of these:

When the encoding is done, I get a ~600MB file and that's the size I got while I was able to use NetVideoHunter so for some reason, rtmpdump downloads a lot of useless information.

I also tried to add the "-W" argument (I found 2 player links but it doesn't seem to work). Here is the html code of the div element which contains the video.

I am open for any advice/suggestion! Thanks in advance!
