i picked up an apple TV with an HDMI cable.  my TV is an older model (only VCR connections and the RF port).  The TV is hooked in through the RF cable to a Comcast Scientific Atlantic DVR box (Exporer 8300HD).  The Comcast box mentioned has an HDMI port on the back.  this port is unlabled if it is an input or output some my assumption is that it is a two way port. 

 

well, i get nothing from the apple TV. I do not see an input selection on the box and the input button on the remote doesn't seem to toggle anything.

 

Comcast was not much help as they kept saying that i select the input from the TV itself, which only makes sense if i was hooking it up to the TV.  I was trying to use the cable/DVR box as a pass though, like how we use to connect cable TV to TVs that didn't have an RF port, but had the composite ports.

 

any ideas on what to try next?

    The HDMI ports that you mention on your various devices are unlikely to be input ports, and even if they are they are less likely to be able to convert the HDMI signal from the Apple TV to the type of connection you are connecting to the TV with.

     

    Short of changing your TV, you may wish to consider a converter, however converters come with their own problems.

     

    There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.

     

    HDCP

    HDCP compliant converters will not allow you to watch HDCP protected content such as that from the iTunes Store. Non compliant converters exist but we cannot discuss them under the Terms of Use for these communities.

     

    Resolution and aspect ratio

    I'm not aware of any converters that will scale the output from the Apple TV, any TV or projector which is used will need to be widescreen and support resolutions of 720p (Apple TV 2).

    The HDMI on the Exporer 8300HD is an output.

    Review your bill with comcast. Your set-top box is "too" much and you are likely over paying.
