Upon more investigation I have discovered that I did not buy an amplifier,
I bought an equalizer with a very poor amplifier. I thought I needed an
amplifier as the DVD player has more cable and works fine. But with this
little repeater, booster, amplifier sitting inline next to the projector
the system is working as long as I use my audio stripper to drive the line
at the computer end. The HDCP splitter will not drive it. I bought a new
splitter that claims it can drive longer runs just to see. These boxes are
all cheap, all under $20. My old splitter that worked great for 720p but
not for 1080p was $350. It had the advantage that it would allow a DHCP DVD
player to work with a non DHCP projector and as at the time my projector
was non DHCP and my DVD player was broken it was the cheapest solution.

Just a note. The $20 audio stripper passes the HDMI and strips off the
audio and sends it to my preamp over an optical cable. That solved the
problem that my new setup would not put out both HDMI and SPDIF audio at
the same time.
