+Alternatively, you can supply different sound files by clicking the
+<guilabel>Use external audio</guilabel> button and choosing a WAV file
+for any channels that you want to appear in the DCP. These files can
+be any bit depth and sampling rate, and will be re-sampled and
+bit-depth converted if required.

+DVD-o-matic will extract subtitles from the content, if present, and
+they can be ‘burnt into’ the DCP (that is, they are
+included in the image and not overlaid by the projector). Note that
+DVD and Blu-Ray subtitles are stored as bitmaps, so it is not possible
+(automatically) to use non-burnt-in subtitles with these sources.
+Select the <guilabel>With Subtitles</guilabel> checkbox to enable
+subtitles. The <guilabel>offset</guilabel> control moves the
+subtitles up and down the image, and the <guilabel>scale</guilabel>
+control changes their size.

+Future versions of DVD-o-matic will hopefully include the option to
+use text subtitles (as is the norm with most professionally-mastered
+DCPs).
