Hello I noticed that orbit/grab++ won't work anymore with cam4...
I tested GetFlv and freerip but Orbit that was definitely the best. Stable, intuitive, friendly interface, simple and you could choose what to rip.
All the others I've tried are not stable at all, they downloads anything for which they are triggered, no intuitive if etc.
That being said the best I have found so far is
http://www.flashrip.com/ although unfortunately you will need the full version.
bye
