I have a MPEG4 video in an MKV container, but it won’t play the video, just black screen. Audio is working though.

The data for the video are this:

Format : MPEG-4 Visual
Codec ID : V_MPEG4/ISO/ASP
Codec ID/Info : Advanced Simple Profile
Duration : 1h 13mn
Bit rate : 1 169 Kbps

Compression mode : Lossy

Edit:  I’m using the current firmware 1.07.18 on the WD TV Live SMP.

Nothing seems to be worng with the encoding.  You may try playing back the file from a USB drive.  You can also reset the SMP by holding its reset button for 1 second, if issue persists try re-encoding your file with a different software.
