Hi, I also just joined this forum. I have Family Tree Maker 3, so I can't answer your question directly, but I found this Magic Guide helpful when importing my media.
Part B implies that if your FTM version is prior to 2012, you won't be able to export the media links using GEDCOM and reconnect them in RootsMagic. RM doesn't reconnect the media automatically in any case. I had to follow the steps in Part C of the guide to get photos and documents to appear in the appropriate locations. Hope this helps a little!
