Yes you should be able to import music and photos in the authoring section of Womble. Not sure why it isn’t recognizing your files. What extension do they have now? .vro?
I downloaded the manual and it shows support for .vro files, if that is what you have. You can always try changing the extension to .mpeg, which works most of the time for .vob files, but I haven’t tried it with something out of a camcorder.
I generally work with tv captures, and edit with VideoReDo, but Womble has more features as an mpeg editor, which is why I suggested it.
