I've just upgraded from V2.1.5 to V2.2.0 and the new version claims that WTV (Windows Media Centre) files are corrupt and won't open them. The same files would open with V2.1.5 and still do after I uninstalled 2.2.0 and reinstalled 2.1.5.
Looks as if something in the new version has broken WTV support. I don't have computers with other operating systems so I can't tell with the problem also affects Linux, Mac OS or Android.
By the way, when will the bug that I raised over a year ago be fixed: that VLC will not display the subtitles in WTV files, even though it recognises the presence of the subtitle stream. This is for WTV files recorded in the UK, with DVB embedded subtitles. If the WTV is converted to TS, the subtitles in that display fine.
