Improve the OSD when using VMR-9 (windowed) renderer.
Fix: Play > Subtitles menu sometimes showed the wrong track as selected.

If the subtitles track was changed at the splitter level the Play >
Subtitles menu wasn't reflecting the change correctly.

DVB EPG: Some strings weren't correctly displayed in some cases.

Null-terminated strings weren't correctly handled.
Cosmetic: fix typo "lenght" instead of "length".
