At the demo version that we use it is possible to use all types of files as input but, using specific

types of files, causes some problems in the output file. After some tests on the file types, the

files that are the most suitable for use, as input, are the “.mpg” files. So, before you use this

program, if your files are not already in “.mpg” format, it is advised to convert them. You can do

this using an online video converter, where you choose the output format that you wish, you

upload the video, it processes it and then you download the converted output video. The site is

http://video.online-convert.com.

In order to create a multiplexed transport stream you need a video file and an audio file. In our

case we used some videos downloaded from youtube and some videos created by the “Roxio

Easy VHS to DVD 3” device so, we needed to demux them and separate the video file from the

audio file before we use them. The software that we were using could separate these files,

something that was very helpful.

The guide that follows shows how to demux the videos and how to multiplex the demuxed files

into multiplexed streams.

Let’s suppose that you have a video called “Learn a language in 6 months”. It is already in

“.mpg” format so we are going to add it directly to our software and demux it to get the

separate video and audio files.

You open the Elecard Xmuxer program and you switch to the “demux” tab. You can click “add”

button and search for the video or you can just “drag and drop” it to the left panel. The left
