I burn 16bit, 24bit, & untracked flacs to dvd (all quality TY disc). 16 and 24 bit flacs are also backed up to at least two externals harddrives (kept in fire and h20 proof safe) in addition to the internals where I use them for the squeezebox. I too am thinking about dropping the burning of the untracked files. I have never gone back and needed them. for shows that I was the only taper I think I should keep them but once I seed the 16&24 bit flacs so they are out there without errors then it's starting to seem pointless keep the raw files.
