I just tried the new version, and nothing has changed, the Proxy Server feature does NOT work.
I got a response back from DVDFab last night, and the person responding did not understand me at all.
They actually sent me my email and password to their web site, thinking that this is what should go into the DVDFab username and password fields in their 'configure proxy access to the Internet' dialog.
The username and password are for the proxy server, and have nothing to do with DVDFab.
They asked me if I could reach their web site thru Proxy, and FireFox can do this easily, as it's not blocked and understands how to use a Proxy Server.
I sent them images for both FireFox's Proxy setup and DVDFab's, and hopefully their tech support will route me to someone who understands Proxy Servers a bit more.
My guess is that they used some open source or 3rd party dll for connecting to a proxy server, without fully understanding how it works, as ... as I mentioned, it never even attempts to connect thru the Proxy (I'd see the attempt whether it passed or failed).
It DOES attempt to use a broadcast address (not a specific computer's ip address, but the address used to query ALL the computers in a a network) for Port 137 NETBIOS Name Service - which is generally used to see what network shares exist (never needed by an application that just wants to connect thru the Proxy to the Internet). This is not good.
Hopefully this will get resolved quickly. DVDFab's developers are top notch, but ... possibly only in their field of expertise, and not in network connectivity?
I well understand this problem, especially when I try things outside MY area of expertise. You can only wear so many hats.
