did you make a batch file for rtmpdump to run and are you sure you got it workin the right way with your network adapter, and you did install winpcap too?
you may want to manually set up your network adapter and you may also have to reboot to get it working.
if you got this far you only have to make the batch file and start testing.
the video will most likely be streamed through a player, so you will need to use the url to the player too in the batch file. the stream will most likely also be halted, and if it does, you need to add the "resume" parametre to it and run the file again and again from a Dos prompt until it tells you it's "done"
if you have problems, try to search for tutorials on this. i know there is quite a few out there. getting someone else to do it, sounds like hmm... not so smart.... :shifty:
from a quick search i came across FVD Suite, maybe that is worth testing..
if nothing works, you still have the Screen Recorder option left...
