I truly have to agree with David on this one. Keeping the bits safe is the priority

Whether or not at some point in the future there is a risk of format obsolescence, the files need to be extracted and put some place reasonably safe, as soon as possible. At this stage, worrying about formats is a waste of time and effort. Worry about formats after you have all the bits safe.
It is truly amazing how each and every discussion of digital preservation gets hijacked by the "OMG format obsolescence" meme.
