FlvRecorder-does what the name implies,records those hard to get protocols,i.e. RTMP
Net Transport-use it every day
HiDownload-Has more features than Net Transport,download youtube,google,etc,but for some reason
i just don't use it as much as Net Transport
VideoGet-downloads from a whole variety of online video sites then converts them using ffmpeg
Out of all of these i use Net Transport everyday,just more fluid,been using it for few years now.
A download program i want but is just too darn expensive is Replay AV,nice features but $49.95 !
And of course all of these would almost be worthless to me if it wasn't for Urlsnooper.
