Last night I converted from .mpg to .asi, MPG4 and MOV using PRISM. In each case the conversion was successful and I was able to play the resulting file with video and sound. I then tried to burn DVDs using Express Burn Plus Demo. In each case the encoding took place and a disk was burned. However, in each case all I got was sound and a black screen. I now have a stack of coasters. Any suggestions? What encoding methods should I be selecting? Thanks much.....
