You state on your web page your Total Media Converter will take itunes videos and convert them to, for example MKV format. I would like to take videos I have purchased, convert, and put on a media drive to watch on TV without having to use a Apple device as the play source.
Does your software perform as your web page states? If so what is the trick?
If you tell me I have to purchase the product to enable that feature it undermines a trial of your product.
