Hello, I use Ulead DVD MovieFactory 6 to create DVD's and their menus, I recently had to work with some *.mpg files with "mp4v: MPEG-4 Video" video codec and "mp4a: MPEG-4 AAC LC" audio codec.
The problem is Ulead DVD MovieFactory 6 is unable to load the file, when I usually have this problem I use VirtualDub to convert the file to another format/compression but VirtualDub is also unable to open the file, I can watch it just fine with Media Player or Bsplayer wich led me to believe the proper decoders are installed (although Gspot reports "Codec Status Undetermined").
What is my problem? Do I need some special codecs or some special video editing application? And if any which do you recommend?
