One more time, lots of googling and this seems to be my problem. Is
there any way to set the audio and video interleave?
The Roku Box does not support playing content that does not interleave
the audio and the video. Content that does not sufficiently interleave
the audio and video will show symptoms of constant rebuffers after a
certain amount of time into the stream (typically ~15-60 sec into the
The maximum amount of contiguous video that may appear without audio
must not exceed 5 megabytes and ideally should not exceed 1.5 megabytes.
The maximum amount of contiguous audio that may appear without video
must not exceed 512 kilobytes. In order to meet these constraints, a
good rule of thumb is that the audio / video interleave should be less
than 5 seconds.
