I used a higher bitrate than normal on this video and a much higher bitrate on the Bill Atkinson 'WheatMan' video and the slideshow. Therefore unless you have a fast ISP/network connection and local traffic is fairly light, these videos may be more problematic to stream. Kevin streamed all of them via AirPlay/AppleTV and had no problems.
If there are lots of complaints about streaming, I will lessen the bitrate but sadly, Purple does not deliver scalable video.
