I can't run my HDMI cable from my Comcast Motorola Box DCT-66412 to my
Pioneer Elite Receiver VSX82TXS I get and error message which says
Comcast does not support HDMI switch. Has anybody got a fix for this
problem? HDMI only works when I connect to the TV from the Cable Box. I
really want to use the HDMI in my receiver I think that would be the best
set up. I went to Comcast's web site and here is what I got:
Some cable TV set-top boxes with HDMI outputs don't deliver a picture
displays with HDMI inputs. What is the problem, and is there a
In some cases, the set top box software does not activate or support
HDMI port. In other cases, cable TV set-top boxes don't work correctly
used in conjunction with an A/V receiver (but will typically function
correctly when connected directly to a TV or monitor). Investigation of
of these devices reveals that this is caused by an error in the way
set top box devices implement HDCP. Specifically, some of those boxes
support "HDCP repeaters" (devices that pass along the signal to another

resolve these problems. We suggest that users contact their cable

My set up is the following
Pioneer Elite Receiver VSX82TXS
Pioneer Elite DVD DV-46AV
Sony Bravia 40XBR1
Motorola DCT-6412 lll Digital Cable Box With DVR
What do I need for this problem to be fixed?
Simple upgrade the firmware on my box. I am running 12.31 now what's
needed is 16.20 Who at Comcast can tell me when will we in DC get this
upgrade. I've learned that Comcast has upgraded other parts of the
northeast. I'm looking forward to your reply.
