RTMPE file download

[drbmn]

I have a file to download whose parameters I copied are as follows :

flashvars.StreamingServer = "rtmpte://gateforum.bc-s.cdn.bitgravity.com/cdn";
			flashvars.File = "/gateforum/protected/eGATE_Archive_Nov/CS/CS_11112013_PI.mp4?e=1384935399%26h=771b90da1ea1ac60670a2eba31d13977";
			flashvars.Mode = "stream";
			flashvars.AutoPlay = "true";
			flashvars.LogoPosition = "topleft";
			flashvars.Thumbnail = "http://www.gateforum.com/Flash_files/eGATE_Videoimg.gif";
			flashvars.ScrubMode = "simple";
			flashvars.BufferTime = "10";
			flashvars.LogoImage = "http://www.gateforum.com/images/egatelogo.jpg";
			flashvars.ColorBase = "#FFFFFF";
			flashvars.ColorControl = "#666666";
			flashvars.ColorHighlight = "#7FBF3C";
			flashvars.ColorFeature = "#7FBF3C";
			var params = {'wmode':'transparent'};
			params.allowFullScreen = "true";
			params.allowScriptAccess = "always";
			var attributes = {};
			attributes.id = "bitgravity_player_6";
			swfobject.embedSWF(stablerelease, "bg_player_location", "720", "480", "9.0.0", "http://bitcast-b.bitgravity.com/player/expressInstall.swf?wmode=transparent", flashvars, params, attributes);

<object id="bitgravity_player_6" width="720" height="480" type="application/x-shockwave-flash" data="http://bitcast-b.bitgravity.com/player/6/bitgravity_player_v6_1_14.swf">

I tried downloading the file using the command

rtmpdump -r "rtmpe://gateforum.bc-s.cdn.bitgravity.com/cdn" -y "/gateforum/protected/eGATE_Archive_Nov/CS/CS_11112013_PI.mp4?e=1384935399%26h=771b90da1ea1ac 60670a2eba31d13977" -o CS_11112013_PI.flv

I successfully downloaded the file but I think its distorted. Most frames are repeated and audio at some specific timespamps are misaligned. Is that because of the command I used to download the file or is it the problem with the website.

Also the video plays in the browser very smoothly without any repetitions( and I am using Windows 7)

Its a premium website for some exam coaching...if I share the username and pass I am gonna get screwed.

Also I used GetFlv to download the file and its working fine. But its very buggy and sometimes the download gets stuck

I want to do it using rtmpdump way. please help me. I think whatever parameters is shared is enough for generating the rtmpdump command, if anything else is needed please let me know. Its very important........
