Movies

[Red Devil]

I included some movies as .avi files in a presentation but when I reopened the file the links had gone and there was just a blank screen. How do I put in links which will stay there? What am I doing wrong???

Must be something obvious - I have been using Writer for a while and this is my first go at Impress. So far I am not missing Powerpoint! Impress looks good for the basic presentations I tend to use!

Thanks for any help!
