rtmpdump error downloading ESPN3 replay video

[sportsfan511]

Hi,

I'm trying to save ESPN3 replay videos from http://espn.go.com/watchespn/index#type/replay/ using rtmpdump, which I've done successfully in the past (about a year ago).

First I start rtmpsrv and then click on a video I wish to download. Next, rtmpsrv begins outputting rtmpdump URLs and I quickly copy and paste the one I want into another virtual console and hit enter, but I keep getting error messages, such as ERROR: RTMP_ReadPacket, failed to read RTMP packet header

rtmpdump -r "rtmp://cp88998.edgefcs.net:1935/ondemand/?auth=daEbwahauc8docRbfbDb2cAchazc.bYb9bd-bsbS6b-8-4xAnwLDFu&aifp=v0001&slist=88998/espn" -a "ondemand/?auth=daEbwahauc8docRbfbDb2cAchazc.bYb9bd-bsbS6b-8-4xAnwLDFu&aifp=v0001&slist=88998/espn" -f "LNX 11,2,202,275" -W "http://assets.espn.go.com/[[IMPORT]]/livepassdl.conviva.com/ver/2.71.0.13109/LivePassModuleMain.swf" -p "http://espn.go.com" -y "mp4:88998/espn/2013/08/07/176-154937/web-encodes/1028277_espn_2200k/1028277_espn_2200k.mp4" -o 1028277_espn_2200k.flv

I've tried the above as well as many variations of it, going on information I got from searching other threads, such as removing the auth string from the "-r" argument and removing things from the "-W" argument so it's just "http://livepassdl.conviva.com/ver/2.71.0.13109/LivePassModuleMain.swf"

I understand the auth string only lasts a few seconds, so every change I make is done very quickly using copy/paste methods to alter the rtmpsrv URLs in hopes that they will work, but nothing seems to pan out.

Does anyone have any ideas? Thanks for any help you can offer.
