I have asked a question several days ago and nobody replied to me, even after 2 messages I posted to request a reply ...

Can someone tell me where and what I should modify to make that Kodi DSPlayer would play DVD ISO files and would also activate a deinterlace filter ??

Thanks to take a short time to help me with that ...

if the stream is flagged interlaced (that's the case with interlaced DVDs) DXVA deinterlacing is used at least with default settings. to get this you have to do nothing at all.

which player doesn't deinerlaced an interlaced flagged stream?

Is there a way to check how stream is flagged (interlaced, ivtc, etc.)?
I have the same problem.

Mediainfo would tell this. If you see interlaced effect (horizontal line) it's usually bad encoded (encoded interlaced source as progressive without deinterlacing).

Actually you should tick enable yadif deinterlacing with LAVFilters. It'd works with all files with interlaced flag.
