Showing local IP Camera does not work anymore with 7.x

[IpCamFan]

I used version 6.1.1, showing the video from a local IP Cam,
with fixed IP address. This works.
As soon as I use 7, 7.1 or 7.1.1 it does not show the video anymore.
If I uninstall 7.x and install 6.x - then it works again.
I created a very simple basical app for experimenting,
which consists only of a RVCamera and a RVCamView,
I can not get it run.
Also the demos do not work anymore with the 7.x, they do not find my IP cam anymore.
As a comment, my ip cams, provide a mjpeg picture, only every 10 seconds, so they are streaming slowly.
Anything that I should specificly change in the properties,
to get it run? I tried already a lot, but without success.
Can you please help?

Is it password protected?

[IpCamFan]

Yes, it uses password. I setup like this:
RVCamera1.CameraHost := EditIP.Text;
RVCamera1.CameraPort := StrToInt(EditPort.Text);
RVCamera1.UserName := EditUserName.Text;
RVCamera1.UserPassword := EditPwd.Text;
RVCamera1.SearchCamera;

A problem with authentication code in our native mjpeg/jpeg reader was already reported. We are trying to solve it (but primary RVMedia developer is currently on a vacation, so most probably it will be solved in the next week).
