Tried to watch the Rugby League on Sunday eve (02/04)
Win7 x64 PC - fairly low spec Brix. Typically uses 50-70% CPU when playing Flash enabled streaming
Firefox - very laggy and juddery @ Full screen - had the clear the cache before I was even to get the Play icon to show up
Internet Explorer - had bits of menu remaining etc when going to full screen, but not laggy.
Installed Chrome, enabled Flash, all went as well as expected for a skygo stream. And the Warriors won :-)
