Did you search the list archives for directv or drd435rh?  I have the 
same receivers working on mythtv for about the last 4 years.  Made my 
own cable from dtvcontrol.com like you already found.  Originally I used 
the rca_control.pl script but when I added a d12-300 to the mix I 
changed to the directv3.pl script here: 
http://www.mit.edu/~je18337/directv/directv3.pl .  For the RCA box use 
'/usr/local/bin/directv3.pl l box_type RCA port /dev/ttyS0.  Change the 
port to whatever serial port you are using.  Here is an old archived 
page that I need to seriously update, but there may be useful info in 
there for you: http://thegeorges.us/mythtv/directv.html .
