Thank You Kevin,
This has and still is a frustrating ordeal.
While I was waiting for an answer, I called Dell Support. They informed me that I do not have a graphics card but an Intel: Intel_Chipset-Software-Insta_A01_R301321. So he pointed me to their latest chip set update. I was a bit comprehensive installing it, but finally did it. Still got my same memory error. I called Microsoft and they wanted $149 to fix my computer (they thought I may have a virus). I got angry and thanked them for their No Service!
I then rummaged around on the Microsoft Community for Movie Maker and "Not enough Memory". I saw where someone suggested to split the array of photos into 2 parts. I did this and now I have both parts saved in the suggested High Resolution (1400x?, MP4 Video Format) and the DVD resolution (760x?, Windows Audio/Video File Format).
Next step, using the Microsoft DVD Maker program I used last year, I burned a DVD with the 2 High Resolution parts. It burned OK, but the photos are terrible and distorted in the vertical direction. What I found later by the name, the program actually took the DVD resolution parts. I found out Microsoft DVD Maker does not use MP4 Video format files. How it used the low resolution movie is still a mystery to me.
I am writing all this to you so someone might benefit from my experience.
Still have to produce a decent looking DVD.
Thanks, Evelyne
