What network will the hercules webcam work on best......skype? msn? what do you recommend?

Try updating your web cam driver from the manufacturer's website...

Go to the logitech website.
Install the drivers for your particular model of webcam.
Usually this comes with a software...
This will get you working your webcam correctly

Now,
Seeing your sis depends on the software you are using to talk with her.
GTalk, Yahoo messenger, msn messenger, Skype etc. will allow you webcam data transfer...

Skype is free and i would recommend that. Just sign up. Its free.

I suggest to reinstall the driver and see if the issues reappear ..remove all trace of the driver in computer by uninstalling it and delete the folder in program files ..and after that install it clean ..It may be a virus or something in conflict so only use it single when you capture..
another advice is to not use the am cap installed with it ..but use it in windows movie maker .and you will have a better control and ability to edit the product ..

Before you can use your webcam in any chat program you have to configure it to that program

Test your webcam here to make sure it broadcasts ok - Hit 'Allow' in the top window and check your cam in the left hand panel.

working OK ?

CONFIGURE TO SKYPE
Connect webcam
Its good practice to disconnect and re-connect your webcam before you start (To reboot the webcam software) - if you have been using it elsewhere the SKYPE software may have difficulty in locating it, even if you exited the previous program correctly.
The reason being, the webcam software can remain hooked-up to a program and needs to be rebooted.
Mine, I just unplug it from the USB and plug it back in to reboot the software.
If yours is integral with the computer you will have to re-start the computer, use a keyboard shortcut or disable / enable the webcam from the Device Manager.

Start Skype.
On the 'Tools' menu, click 'Options'.
In the navigation pane of the Skype 'Options' window, click 'Audio Settings'
Run down the list setting your defaults
Select your webcam as the default microphone.
Make a free test call
Click 'Save'
In the navigation pane of the Skype Options window, click Video Settings.
This will launch your webcam
Adjust quality of picture in 'Settings'
Check the correct webcam is shown as default
Click Save
Test your webcam by making a Skype test call.

CONFIGURE SOFTWARE to MSN
Its good practice to disconnect and re-connect your webcam before you start - if you have been using it elsewhere the MSN software may have difficulty in locating it, even if you exited the previous program correctly.
The reason being, the webcam software can remain hooked-up to a program and needs to be rebooted.
Mine, I just unplug it from the USB and plug it back in to reboot the software.
If yours is integral with the computer you will have to re-start the computer, use a keyboard shortcut or disable / enable the webcam from the Device Manager.

Then download the program and install it to start having fun with your camera and friends.

Manycam allows you to use your Webcam with multiple programs at the same time. Broadcast your
Webcam on MSN Messenger, Yahoo!, Skype, AIM, Paltalk, and Camfrog all simultaneously. Manycam
also allows you to add cool live CGI (computer generated special effects and graphics) to your
Webcam. Make it appear as if your face or hand is on fire with our "fire" effect.
Pretend you are underwater or make it look like it's snowing inside your house with the
Manycam underwater and snow effects. Add text, graphics, or your country's flag to your video
window.

ManyCam is the freeware tool for you if you use both CamFrog and ICQ, or any other video chat
program, and you want to use them simultaneously. It creates a "virtual" Webcam that
replicates your currently installed camera. It then lets multiple applications
access the video stream without conflict.

ManyCam is compatible with Yahoo, MSN, CamFrog, PalTalk, ICQ, Skype, YouTube, and more. Once
you've installed ManyCam, you need to set ManyCam as the primary input for program that you
want to use. ManyCam will automatically start when you activate your Webcam through that
program. The application includes a bunch of gimmicky features that let you change aspects of
the background and foreground. You can map a new pair of cartoon eyes over your face, and they
track pretty well to your movements, or you can show that your life is hell by replacing the
background with flames.

NOTE: There is an unfortunate toolbar that will install unless you opt out during setup, but
other than that ManyCam is worthy of a Webcam Oscar for cool and useful tech.

Hope this is of some help. Bud

Normally you can do video call.
While chatting and enable the video is possible with the latest version of skype 4.1.0.179

Another options also is to use is use a other software for video like msn or yahoo messenger.

try also msn with the webcam configuratie if thad works skype wil work also

u need to select it in the settings
i have had my webcam on skype running ok
but when i use msn for video it freezes my pc so i dont use it on msn

Yes. You need to use the same program in order to talk with each other. Also, in my experiences with webcam setup and the different program carriers to use for best picture quality, I use Skype. I tried AOL, Yahoo etc. and Skype worked the best. You can have the best webcam on the market, but if you don't have a good carrier, the picture quality and sound can still be affected. Since your friend already has MSN, try that yourself and see if it works out for you. Good luck!
