Greetings Tate,
Yes you can, although in order to do video with a Windows Messenger client, the MSN Messenger
user must be using Windows XP.
There are several differences between the two. Most notably, MSN Messenger 6 has support for
display pictures, custom emoticons, has a different interface, etc. whereas Windows Messenger
supports SIP-based communications services, Exchange IM Server, etc. Which one you use is up
to you, and a matter of personal choice (and based upon your needs and likes), however one
thing to keep in mind, Windows Messenger must still be installed on
Windows XP in order for MSN Messenger to retain full functionality (Remote Assistance,
Whiteboard, Application Sharing, etc.).
MSN Messenger is centered around MSN technologies (Hotmail, MSN Member Profiles, MSN Mobile,
etc.) whereas Windows Messenger is centered around Windows technologies (Exchange Server,
Office Live Communications Server, Windows Netmeeting, etc.).
Both clients however can make use of Microsoft technologies, like the .NET Messenger service,
..NET Passport and .NET Alerts.
