VLC for Android Sony Bravia breaks video for DVDs enveloped in ISO image

Hi, I use VLC on Sony Bravia TV with Android - I try to use the latest version of Android, so I already tested this bug on two different versions. VLC plays my old DVDs that are ripped into ISO images. This you very much for this feature. On the Windows laptop, there is no problem with the playback. On the Android, the video plays about 10 frames per second, all interlaced (video is "combing"). There is no setting in the VLC for Android to explicitely turn on deinterlacing, and apparently the player does not recognize itself, that it should deinterlace. The TV has definitely enough power, it plays much more computation-demanding videos. The source video is standard PAL, 25 frames interlaced, 576 rows. This happens for all ISO images that I have.
