Myxamatosis

In sonicstage when i try to select the files i want to convert to atrac3 using the Tools > Convert Format option, the tab is greyed out no matter which bitrate .mp3 is selected. *edit* I have figured out why this is. The individual files have to be selected in order to use the convert format option. You cannot convert an entire album at once by right clicking the album. On a side note does anyone know if its possible to convert .mp3s into the new atrac lossless format? And would doing this conversion from .mp3 completely remove the small loss when converting .mp3 to atrac? Thanks,
