To backup your firmware, it's best to look at the "Knowledge Base" section on this site. There is a link on the left hand side menu bar.
Boosting the volume, you will need to look at using another program to increase the volume of the original video file before converting it as the AMV Convert Tool doesn't have that option. You can use "PocketDivxEncoder" to do this. It's available in our "Downloads" area under the "Tools" section.
Good luck and welcome to the club of MPx users
