No - the HD channels are on the list.  If I am using the Input Source 
for live TV (switch to it using menu) and switch to a normal channel I 
get the channel properly.  However if I change an HD channel (which you 
can ONLY do with this device as the source) Then the screen just doesn't 
display anything except what appears to have been a graphic from the 
previous channel I was watching.

If I try and record an HD program, the recording length is 0 bytes long.

I am wondering if its a hardware failure (given the non HD channels work 
fine) - but I have no idea how to check that out and prove it.  Anyone 
and ideas?
