Pre 3.0 most people put the epg images and sound files under the dvdprofiler directory calling it epg.

Now, not surprisingly this has changed.

For me using XP Pro mine now have to go here :-

C:\Documents and Settings\ajm\Application Data\DVD Profiler

replace 'ajm' with whatever your username is called. This is for XP Pro may be different for other windozes versions.
