I rendered an MP4 source video in Sony Movie Studio 15 Platinum to two different outputs:

* 1240x400 MP4
* 248x80 MP4

The 1240x400 MP4 plays fine in VLC and Windows Media Player under Windows 8

The 248x80 MP4 - rendered using identical settings except for the target resolution - plays in the Windows Media Player but in VLC just displays as green squares that blink.

What would cause this to happen and is there a VLC setting to adjust?
