Hi [B]joyce.joyce[/B], and welcome to CD Freaks.
I moved your post into the main part of the Newbie forum, where you will probably have a better chance of getting some help.
There’s not much information available on that frame; only the standard manufacturer’s blurb and no reviews that mention containers (which is what ‘.avi’ is) for moving-image formats. True, it does say MPEG4 but the acceptable containers for that might be restricted to .MP4 or .WMV. I think your best bet is to load some of your .avi clips on a memory card and take them down to a shop nearby that sells these things. Ask them to demonstrate it with your own movies.
