Thank you very much for the rep! It is my pleasure to help you! MediaCoder really is a great little program. And, as you were able to do, it gives you full control over the output of your file.
MediaCoder does use the Internet every time that you use it, but it only uses it to detect for updates. And every week there seems to be an update to it. Lol, the guy behind MediaCoder has been really working hard ^_^. Once you update MediaCoder, you will also see that your web browser will open, and there is a button on the page that says something like "Start MediaCoder". Beneath that, there is a check box that says something like "Don't show this window again". If you check that box, then click the "Start" button, then that window will not open until you update MediaCoder again.
So, long story short, you do not need to be connected to the Internet for MediaCoder to work. It only uses the Internet for program updates.
I hope all goes well ah.ni.may! If you ever need more assistance, please don't hesitate to post on the forum or send me a PM.

Thanks again for the rep and happy coding!
