MediaCoder I really like, especially the update method. For the uninitiated, you can download a full new install of the program, or just a much smaller "update" file.
There is, or was, bugs in it. One in particular was trying to use the "Extension" radio button. Always tripped with that, but the most recent update seems to have cured it.
I've read the "Super" links you posted, and to be honest, I kept it but never use it now. And it's probably the old type install.
I'm gonna remove it with the latest Revo Uninstaller, and see where it's got stuff installed.
There isn't anything I do that I need it for anyway. Kept it in case it came in handy.
Between MediaCoder and Avanti, I think I've got all the stuff I do covered. Let me know what you think of Avanti.
