and i just had a question. so these programs: avi synth and ffdshow, u just dl and install? u don't actually need to open them /manually use them when your creating a .dpg via batch or whichever other program? if someone could give me a brief explanation what purpose do they serve, do they install themsevles and always run in the backround or somthing? Edit* i started the conversion, and when i go to the temporary folder, i see 2 files, a video and audio, do these come togather in the end?
