In the PC start menu find the RUN icon, open it up and in the data entry box type CMD, this will open a DOS prompt window. At the cursor type "ping xxx.xxx.xxx.xxx" where the x's are replaced with the IP of the iPad. Also remember that the laptop and the iPad must be in the same range, the address segments MUST be the same except the last segment EG laptop 192.168.000.002  iPad 192.168.000.003 if they do not match they will not be able to talk to one another.

The address in the desktop version needs to be the same in the iPad configuration window in the app (not the same as the IP of the iPad itself) including the port, personally I never set a password in the desktop because I am the only one using the program and it is on my internal network, so as far as I am concerned it's just another thing that can go wrong. I left the port at the default. Update that and see if you can connect.

BTW I was never able to get it to work using the PC name in the app, but the IP worked fine.

O.K. I am on my home network now and still unable to connect.  I do notice that my iPad under network connections shows a different number than the one that reads at the bottom of DVDProfiler on my laptop.

Yes the DVDProfiler under tools option sharing matches what I have on the iPad DVDProfiler, I have used the same ip address that I read at the bottom of the DVDProfiler plus the default port and "Unable To Connect" is all I get.  I have tried port 80 and 8080, antivirus off firewall off and nothing.

GREAT!!!

Is it possible to get both routers on the same password, at least that should make life a little easier for you. Or when you move the iPad from one router to another you should set up two different networks in the iPad so that you can select the one you want and each one can have a different password

I'm guessing here but I think that unless you have two different Wi-fi network setups in the iPad with the two different passwords the pad will only be able to connect to the one it can uncrypt.....
