thanks for the info. have you verified that this link works with rtmpdump?
If the downloads cut out it s usually a case of it using swf verification and you have to provide the swf path in the command line. The swf path is usually easy to locate, in this case too. Just use URL snooper running as usual in the background and load the video page and play the vid and it will show up in URL snooper. To filter out the junk, use the keyword filter and search for swf obviously ^^.
A typical command line with swf verification looks something like this:
[copy or print
rtmpdump -o filnamn.flv -r "rtmpe://fmss.vpro.nl/media/mp4:41723347.mp4" -W http://3voor12.vpro.nl/flash/vodmediaplayer-25052009.swf
Hope this helps.
Oh, I forgot to mention. If your video is black but you can hear sound, it s most likely due to your system lacking a video ccodec for proper playback of the video stream. You might want to try out VLC as you default player instead of whatever else you are using at the moment. If yo udont, and want to keep using the player you are currently using, you can try your luck with the K-Lite codec pack. I would recommend yo uto start using VLC tho as it s a very comprehensive pice of software video player with many already built in codecs etc.
