@gary5984 During my off time from AD and work, i played around with nero vision and came to the conclusion that Smart Encode caused failures for me and unchecking it increased the encode time, but got it to work. I also found that converting the files with another program, before giving it to Nero Vision, caused 100% success, while letting Nero Vision convert files into a DVD format caused failures about 40% of the time for me. So i used a program called Advanced X Video Converter to do the AVI to VOB. That program also joins MPG files into one big one. I found Vision could only handle something like 70 titles before it reached its max title limit, but joing small files into one larger one reduce the number of titles. It has a free trial period, but i bought my copy a year or so ago. http://www.aoamedia.com/download.htm Im not saying that is the best way to do it, or that this is the best program. It works for me, and that is what i use for file conversions. Good luck and happy burning.
