Poor performance and timing

[arcfide]

There seems to be some poor performance and timing issues when casting certain things. See http://shelr.tv/records/506fbe479660807d95000030 and http://shelr.tv/records/506fb6809660807d9500002d as two examples. The first has bad timing and the end of the video displays through before it can be read, much more quickly than should be for the timing results. The second fails to display the cursor properly, which is critical to the video.
