can use Airport router and Airparrot2 software to send to an Apple TV

Chrome browser to 'cast' the tab to a Chrome dongle but I suspect the
same result. </font></font>

Am I right in thinking that when using Airparrot2/Chrome browser the
PC has no action in decoding the file merely streaming to the TV? And
that is why we get no sound from PC. Which leads me to think we'll
need to connect the TV to the sound desk via one of the sound input
XLR points.</font></font></div><div style="margin-bottom: 0cm; line-height: 100%"><br>

If we cannot repair/re-run the Cat5 .. is there a (cheap) way of
sending HDMI over wifi?</font></font></div><div style="margin-bottom: 0cm; line-height: 100%"><br>
