yep, if you burn them as a data file you can still open them in cd wave and wavelab. instead of having an audio file, you'll have a data file, just like the one that used to be on the pc hard drive, only it'll be stored on the dvd-r.
I usually make a single dvd-r for a night out, and on it, i'll put the master wav file, the 24bit flacs, the 16bit flacs, sometimes mp3s too, and all the info files and md5's for that disc and an info file about the night, where i sat up in the club/venue, and all the minor details.
