Comcast HD Box and HDMI Repeaters - UPDATES?

[EastCoaster]

Does anyone have any updates on whether Comcast has upgraded the software on its HDMI set-top boxes to allow the HDMI handshake with new receivers?

Does anyone's Comcast set-top box allow an HDMI connection directly from the set-top box to a receiver, and then from the receiver to the TV? (I know it should work if connected directly to the TV, but I'm referring to connection through a receiver, which is an HDMI repeater).

I've got a Comcast Motorola DCT3412I, and it hasn't allowed HDMI repeating in the 8 months I've had it. I'm not sure if Comcast has issued software upgrades... (and they can do it I believe through the Coax).

Perhaps it's worth it just asking them for a new box (maybe it will be pre-loaded with the updated software)? Any ideas?

im probably wrong but i thought i read somewhere that repeaters/switchers worked fine but some receivers didnt. reason being that some receivers had scaling features that the cable box couldnt recognize because it changed the signal the cable box put out when it scaled it? im probably wrong....

The way this works is that the receiver itself is working as an HDMI repeater, but the cable box does not allow HDMI repeating. I have scaling turned off on my receiver - and it still doesn't work.

The problem is that the cable box, the HDMI source, is looking for an HDMI receiver, the TV. The audio receiver is an HDMI repeater. The cable box does not handshake properly with a repeater because most of those cable boxes were made before repeaters even existed in the consumer world.

As far as I know, Comcast has not updated the software. At work we have four Comcast boxes and none of them have worked with any receiver (Yamaha, Pioneer, Denon).

The bit of news that no one is paying attention to, is that it appears that everyone who will be buying a new 1080p television will not be able to enjoy any 1080p content routed through a receiver to a tv until cableboxes do HDMI... This is because component cables can't do 1080p.

I guess maybe a workaround would be to run the HDMI cable from the cablebox to the tv, and then the audio to the receiver... That is, if the tv has two HDMI slots (I am assuming one slot on the tv is already taken up by the receiver to tv HDMI cable that takes care of one's DVD player).

What a mess....

I don't have Comcast, but Time Warner. I received my Yamaha RX-V2700 receiver a few days ago, and tried HDMI from the SA8300HD through the receiver and to my TV.
It worked!
