-There is a limit of 99 "titlesets" (groups of video sequences) on a
-DVD. Currently WebDVD does not attempt to group video sequences
-together, so there is a limit of 99 video sequences altogether.
+There is a limit of 99 "titles" on a DVD. If you need to include more
+than this number of video sequences, you could arrange them as
+chapters of a title, so long as they use the same codecs, resolution,
+aspect ratio and sample rate. However, each chapter will run into the
+next. If this is a real problem, let me know, and I may be able to
+provide a better solution in a later version of VideoLink.

+Bugs
+----
+
+Under Mozilla 1.7, VideoLink sets the assumed screen resolution to
+40 dpi, which I reckon to be the average resolution of a standard
+definition TV display. This should mean that text with a font size
+expressed in millimetres or points will appear around the specified
+size. Unfortunately this setting has a different effect under
+Mozilla/XULRunner 1.8:
+
+Mozilla Assumed Requested Actual size
+version resolution size (pixels) (inches)
+ (dpi)
+
+ 1.7 default:96 20 px 20 0.5
+ 1.7 default:96 36 pt 48 1.2
+ 1.7 40 20 px 20 0.5
+ 1.7 40 36 pt 20 0.5
+ 1.8 default:96 20 px 20 0.5
+ 1.8 default:96 36 pt 48 1.2
+ 1.8 40 20 px 48 1.2
+ 1.8 40 36 pt 48 1.2
+
+From version 0.10, until I have a proper solution, VideoLink will not
+set the assumed screen resolution under Mozilla 1.8. I must advise
+against using font sizes in millimetres or points since they will vary
+between browser versions.
