Hi desperate girl,
so you can download the vids via rtmpdump so its working.Here a short link and command-line of your first and second video (third was not playable on the website at the moment)
Code:
rtmpdump -r "rtmp://cp44293.edgefcs.net:1935/ondemand?//public/unsecure/1500kbps/2c97c59342dbb99b014348a3326a4431--video--Martin-FINAL_flv_avc1_high_int.mp4" -o "video.mp4"
rtmpdump -r "rtmp://cp44293.edgefcs.net:1935/ondemand?//public/unsecure/1500kbps/2c97899442dbb86b01430c192f0b3fad--video--VinylRiches_flv_avc1_high_int.mp4" -o "video2.mp4"
So to make it process easier you should use RtmpDumpHelper tool so just have a look into rtmpdump section and check out the tools you need so that you can handle this steps & downloading by yourself.Just spend some little time with this and then you will get some success (if not send some feedback about your progress).
You can also use other tools as livestreamer for exsample...etc.
