You can also try freeware Orbit Grab Pro, freeware StreamTransport and freeware rtmpdump. The latter program is great, but it is a command line tool, so it can be harder for you to learn how to use it (note that rtmpsuck simplifies the process a lot).

From commercial software I like Replay Video Capture, Jaksta, WM Recorder Bonus Bundle. All these products and bundles are good, but not ideal. Jaksta is cheap, but in my experience very powerful. Other bundles are worth considering because they come with a screen recorder and other software.
