Public bug reported: ### Description of problem or feature request
`Show Preview` plays audio but doesn't show any images, only a black window. I have tried only with DVDs on disk (*VIDEO_TS* directories), around 6 different ones, and it happened the same with all of them. I always used preset `H.264 MKV 1080p30`. I also tried the following previews: `Fast 1080p30`, `Very Fast 1080p30`, `Normal`, with the same results. I ran **ghb** from the command line and no messages are output when I try to show a preview. The encoding works correctly, it's only the preview which is showing no video. I tried to select different preview frames, but the result was the same with all of them I have just tried the latest nightly snapshot, **20180121174120-18a4158-master (x86_64)**, and the results were exactly the same. I have reported this bug upstream and the handbrake team has updated me that the Ubuntu package is known to be broken: https://github.com/HandBrake/HandBrake/issues/1143 ### Steps to reproduce the problem 1. Select preset `H.264 MKV 1080p30` 1. Click on `Open Source` and select any DVD on disk (a *VIDEO_TS* directory) 1. Click on the `Encode and play` icon 1. The preview window will be black, and only the audio will play ### HandBrake version (e.g., 1.0.0) **1.0.7 (x86_64)**, installed from the Ubuntu repositories ### Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.3 High Sierra, Windows 10 Creators Update) Xubuntu 17.10 ### HandBrake Activity Log ***required*** (see https://handbrake.fr/docs/en/latest/help/activity-log.html) ~~~ [18:14:10] gtkgui: HandBrake 1.0.7 (2017082500) - Linux x86_64 - https://handbrake.fr [18:14:11] hb_init: starting libhb thread [18:14:11] hb_init: starting libhb thread [18:14:11] hb_init: starting libhb thread [18:14:16] CPU: Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz [18:14:16] - Intel microarchitecture Sandy Bridge [18:14:16] - logical processor count: 4 [18:14:16] hb_scan: path=/home/paulo/Downloads/The World Saxophone Quartet 2009, title_index=0 disc.c:424: error opening file BDMV/index.bdmv disc.c:424: error opening file BDMV/BACKUP/index.bdmv [18:14:16] bd: not a bd - trying as a stream/file instead libdvdnav: Using dvdnav version 5.0.3 libdvdread: Couldn't find device name. libdvdnav: Can't read name block.
