Problem recording music with Replay Media Catcher at Walmart Soundcheck (rtmp:// flv)

hope anybody can help.
i tried to capture the rtmp video streams from:

http://soundcheck.walmart.com/mandy-moore-07

with Replay Media Catcher and nothing. all i got was the intro video that appears in every session of walmart. the actual songs couldn't be captured, the data received stoped at 0 kb. altough the video played normal on the page. and then this message appears:

"Sorry, could only download a partial RTMP stream"

do i need an extra plugin or something??
anybody? thanks in advance!

oh, and i tried with other programs, like Bit Recorder, WM Recorder, Rip Tiger and it didn't work either.

I don't have any problem recording with rtmp:// .flv videos from soundcheck.walmart.com with Replay Media Catcher 3.0.2. You may read the following tutorial to learn how to record with Media Catcher:

Do you have an older version of Media Catcher?

I haven't tried other above mentioned Flash stream recorders, but Jaksta can record music videos from soundcheck.walmart.com.

i had an older version of replay media catcher. the 3.0.2 version is working fine, thank you very much
