rtmpdump handshake error


 
I am trying to download a channel 4 program from youtube (http://www.youtube.com/watch?v=2hWsfEPdT4g), but it fails with:

Code:
Connecting ...
WARNING: HandShake: Type mismatch: client sent 6, server answered 10
WARNING: HandShake: Server not genuine Adobe!
ERROR: RTMP_Connect1, handshake failed.
Any idea why this is and how I could fix it?

This is what rtmpdump captures - before it segfaults:

Code:
rtmpdump -r "rtmpe://r6---sn-aigezn7k.c.youtube.com/videoplayback" -a "videoplayback" -f "LNX 11,2,202,273" -W "http://s.ytimg.com/yts/swfbin/watch_as3-vflCqc2WH.swf" -p "http://www.youtube.com/watch?v=2hWsfEPdT4g" -y "sparams=gcr%2Cid%2Citag%2Crtmpe%2Csource%2Cexpire&gcr=gb&fexp=920704%2C912806%2C902000%2C922403%2C922405%2C929901%2C913605%2C925006%2C906938%2C931202%2C908529%2C920201%2C930101%2C930603%2C906834%2C913570%2C901451&signature=673C8BE9BC30DD798CF23A2004DCA9368E87B31B.8B7FE1BC427AA3E87389A4952AD1D984B5FEB318&rtmpe=yes&itag=34&source=youtube&sver=3&key=yt1&id=da15ac7c43dd4f88&expire=1362519023?ptk=channel4&ptchn=4oDFood&cpn=BYYl3nVhBZOB5ld1" -o sparams=gcr%2Cid%2Citag%2Crtmpe%2Csource%2Cexpire&gcr=gb&fexp=920704%2C912806%2C902000%2C922403%2C922405%2C929901%2C913605%2C925006%2C906938%2C931202%2C908529%2C920201%2C930101%2C930603%2C906834%2C913570%2C901451&signature=673C8BE9BC30DD798CF23A2004DCA9368E87B31B.8B7FE1BC427AA3E87389A4952AD1D984B5FEB318&rtmpe=yes&itag=34&source=youtube&sver=3&key=yt1&id=da15ac7c43dd4f88&expire=1362519023.flv

Then it just hangs there until I enter Ctrl+c and it exits as follows:

Re: rtmpdump handshake error


 
Guys, could at least someone confirm if they succeed in downloading this video, so that I can investigate my set up further if this is just an isolated case?

Thanks for any pointers.
