Disc rips fine, just without the video track.
I can't even select the video track at all - there's no option.
It picks up the code as MpegH HEVC Main10@L5.1.

Running the latest version of MakeMKV...
Any help appreciated.

MakeMKV won't allow you to UNSELECT the video track, which is why you can't "select" it.

If the video track was not selected and ripped, the resulting file would be VERY small. Are you certain it isn't being ripped? Sometimes the player you use won't play certain video codecs, which will make a video seem blank.
