 Head revision 20658

 When playing a 4:3 ratio DVD (or .mkv with DVD subpicture subtitles) on a
 16:9 ratio TV using VDPAU, the picture is displayed correctly, but the
 subtitles appear scaled to the full width of the 16:9 screen. This can be
 readily seen with wider subtitle text where it overlaps the edge of the
 picture.

 This is not normally a problem for soundtrack subtitles (hence the low
 severity), where the text is merely a little ugly. It can however cause
 irritation when the subpicture has been used to position translations for
 in-picture text (e.g. Japanese/Chinese characters on signs), as these then
 appear in the wrong place and obscuring things they were not intended to
 obscure.

 The problem does not seem to affect normal Xv (non-VDPAU) rendering where
 the subtitles are scaled correctly.
