Hi Charles. I live in a PA

Hi Charles. I live in a PAL region (Australia). I did an experiment last night. I directly exported (File-Export-Movie) a troubled video to an AVI file and It plays perfectly on my new laptop without ANY hitches. So, could the problem be either my DVD burner on my main PC or could there be an issue with Elements 4 when I burn it to DVD. I have used both template setups (Widescreen 16:9 Interlaced & Standard 4:3 Interlaced) and the problem is non discriminate. Also what is the Interlace? i cant seem to change it if I had too! One other thing, is the fact that i am dealing with analog footage have anything to do with the shuddering effect i sometimes get on moving footage? I really appreciate your advice !

many thanks
