MKV file unsupported by WDTV live after changing mkv properties


I have mkv files that were previously working on my WDTV live. unfortunately these were having wrong aspect ratio due to bad values for the display_width and display_hight property of the container.

after correcting theses properties using “mkvpropedit.exe” from “MKVtoolnix” (that means without any re-encoding) I get some valid mkv videos, that play fine on my other XBMC based mediaplayer and on my PC using vlc, but on my WDTV live. I get a “Unable to play selected file. Please see user manual for list of supported file formats” message. the WDTV live is using the latest firmware (v2.01.86).

here’s MediaInfo log for one of the mkv:

Have you tried resetting the media player? If not, please try that. This will allow the media player to read the files again.

Are you playing those files through the network or connecting a drive/flash drive directly to the media player?
