Is your mom computer literate enough for her to join this forum conversation? It will be hard for anyone here to ask questions and make suggestion to you, then you to her, and so on. Or are you located close enough that you have phyisical access to Mom's computer?
What version of Skype is Mom running? She should click on Help > About for the specific version number.
What version of Windows.
What type webcam?
Does the webcam work on with an other programs, or can she see her own video at this webcam test site: http://www.sillywebcam.com/test.htm
edit: Is video and audio normal for you with other contacts?
