RS130 Hifi Rose App cannot see DVD file

Hello admin

I downloaded the DVD from below link (using torrent)
https://rutracker.org/forum/viewtopic.php?t=1247879

Then I copy the downloaded files to my NAS. The “Rose Hifi” app on Mac OS can brow the video to the directory, but cannot display the video files in “VIDEO_TS” directory.

Actual “VIDEO_TS” directory contain files such as “VTS_01_0.VOB”,…“VTS_04_1.VOB”.

The problem is, the app cannot see the file.

Other Blue ray disk (downloaded from rutracker also, The app can see files and play well.
Pls advise
Tks
