How to display DVB subtitles in a WTV file

I have a variety of standard-def WTV files recorded by Windows Media Centre (Windows 7) from various UK broadcasters. How do I display subtitles? I think I've enabled subtitles but no text overlay appears.

It seems to be a bug when reading WTV files, because if I display a TS file which is generated from the WTV file, subtitles are displayed fine.

I'm using V2.0.7 of VLC.

VLC's Video | Subtitles Track is displaying the existence of "Track 1 - English" and Tools | Codec Information shows 3 streams:
0=Audio (MPEG 1/2/3, Stereo, 48 kHz, 256 kb/s)
1=Subtitle (DVB Subtitles DVBS)
2=Video (MPEG 1/2, 720x576x25, Planar 4:2:0)

Other programs such as Windows Media Centre and VideoRedo V4.21.2.665 can see and display the subtitles.

Are there any other settings in VLC that I need to check/change to make the subtitles actually be displayed.

Note that these are DVB subtitles embedded in the WTV file, not subtitles that are supplied in a separate SRT file.

Ah right. Looks as if this is a bug and that as of April, no bug had been raised.

How do I raise a bug so this gets looked at?

I've raised Ticket #9120 on Trac. Let's see what happens.

This is fixed in 3.0

- We don't know which captions are in WTV (avformat and WTV bug) https://trac.videolan.org/vlc/ticket/9443#comment:5
- Shown captions are then extracted from Video stream (avcodec decoder)
- Not on MacOS because hw decoding is using VideoToolbox which doesn't export captions

Wow, that's unfortunate. Any way of doing it with VT?
