<p style="padding: 0; margin: 0; min-height: 11pt; font-family: arial,helvetica,sans-serif; font-size: 11pt;">Hi Jay,</p>

<div>I know it can cut mp4 ts streams… </div>
<div><br /></div>
<div>If ffmpeg can cut h264 and there is a list of cuts in mythtv, it should be able to. I do know that mp4s created from handbrake can not create a seektaable, so cannot be flagged in mythtv.</div>
