You would think I would know I erased the files. I finished a burn of a "test" dvd, (and rendered a backup video), and immediately went back to Videowave to make corrections in audio levels, and when I called up the production file, it reported all the files that were missing. This happened twice! It also happened after a short test production using a random selection of jpgs from several folders...but not all folders "lost" files. For the most part all audio and video inserts were still ok. The program lists the files that are missing, so I am working from those lists to make replacements.
Inyeresting to note that a review of Windows 2011 Movie Maker says in the CONS list that it "silently removes" the data filees. My first suspecion was that the problem is in Win 7, which I am using.
Two things I am concerned about. Any size limitations (other than slow processing) in the data files if they are from 1 to 6 megs...and am I likely to have this problem again. I guess the answer to that is to try another burn with random pictures for minimum time in production. And...certainly I have been told many times that My DVD and Videowave cannot erase the production files. But something did.
