No, you will not lose any contents of a RAM, after transferring it to the pc's hard drive. The DVD RAM compatible dvd authoring software will read the contents of your transferred disc, and see individual titles, that you can select to load in any order when creating a dvd.
Also, any DVD RAM compatible Player software, should also recognize individual titles, allowing you to select say, title 3 to play, rather than starting playback with the first title.
