Hi I'am new to this site but I had the same experince with my daughter who is 9+ month, what I did was not to force her I just let her watch the slide show and I point at her nose, eyes what ever it come in the slide show if she does'nt like you touching her you point at yourself and show her where is nose, eyes..... what ever come on the slide show slowly she will get interest to it. Mean while when ever you are free put her on your lap facing you and teach her simple things like what's on your face and point at yourself first then point at your baby gradually she will pick up. Baby need to know the meaning first for them to get interest then they will enjoy learnign.
My baby in one week time said ball, duck and point at my nose after watching the slide show but I don't really rely on the slide show I always keep on telling word to her while cooking, playing or while bathing.... repetation is the key of success I notice. never force her to watch or do someting which your baby don't like or they will lose interest immediately and don't want to do it anymore. Let your baby take her own time he/she is only 5 month. keep on teaching you will be suprise to see your baby will show something or say something that's what my baby did I was suprise

all the best!
