[mythtv-users] The Death of MythTV in the US?

[allene222]

Splitters are a little different.  They are designed to allow two displays to
sit on one output device.  Maybe a projector and a monitor.  Anyway, this
was not anticipated in the HDCP spec so apparently the only way they can
build these is to strip the HDCP out.  They are not strippers although I
used mine for that and the fact that I needed an amplifier for the long
cable run.  It worked for 6 years until the projector failed.  I was pissed
that it didn't work with the new HDMI projector as I still wanted to use it
as an amplifier.  The projector wasn't buying it and would not display
anything.  They might end up getting blocked but very few of these are sold
so it may not be worth the trouble and, after all, they are not strippers.
