If DVD audio is anything like mastering audio CDs then you may need to make sure it's tracked on sector boundaries.

Um, if this operation is cumbersome then your GUI app is _horribly_ broken. This should be as easy as "File -> Open Append" and select all the files. Even easier than catting them all together. > > 3) I am not sure if have a single 4 Gb wav file would cause playback > problems on a reasonably fast computer with a DVD drive. Should work. Opening a 4GB file should not be harder than opening a 4MB file. The whole thing does not have to fit in memory at once. > My intuition > says yes, however.
