+Acer/Packard Bell is not willing to repair all defects
+on my computer, but at least I can run this for several
+hours and try to revive dead pixels. Playing back a
+video that is already available on the Internet has
+some deficiencies:
+
+@itemize @bullet{}
+@item
+Requires a graphics card and video player that can play
+back the video in full screen mode efficiently.
+@item
+Requires @command{X} or a video player than can play
+video outside @command{X} efficiently.
+@item
+Requires the video to be downloaded if it was uploaded
+on Youtube, because Youtube does not properly support
+full screen.
+@item
+video playback is required per defective monitor.
