Lirc with Harmony 555 and NOVA TD-500 receiver

[Gavin W. <Gav...@st...>]

Folks,

I am new to lirc and need to fill in some of the gaps in my knowledge. 
Hopefully this is the right forum do to that.

In summary....

What I'm trying to do
=================

Drive MythTV (0.22 on Xubuntu 9.10) from my Logitech remote.

The Hardware
============
I have a Logitech Harmony 555. 
The HTPC has a Hauppauge WinTV NOVA TD-500  and a Hauppauge WinTV NOVA HD 
S2.
Both have built in (USB?) IR receivers.  I am choosing to use the TD-500.

The Configuration
===============
I have configured the Logitech Harmony 555 from the Logitech database with 
the WINTV-NOVA-TD-500 device.
I have the standard hardware.conf and lircd.conf generated by the config 
utility which runs when you install the lirc package on Xubuntu.
Running irw on the HTPC all of the buttons produce the correct/expected 
output for both the original Hauppauge remote and the 555.

The Problem
===========
Basically - there aren't enough buttons!
With MythTV there are many many things you can do from the keyboard.  The 
Logitech database entry for the Hauppauge remote only has 50 or so buttons 
- as that's how many buttons there are on the original remote.
How do I get more buttons?

Solutions
========
One thought I had was to ask Logitech if they can provide a database entry 
with more buttons - and I will pursue that separately with Logitech.

The other approach that occured to me is to get the 555 to mimic a remote 
which:
a) has many more buttons
b) is present in the Logitech database
c) sends signals which can be received/processed by the receiver in the 
NOVA TD-500 (or NOVA HD S2)

It's part (c) where my knowledge of IR, IR receivers and LIRC lets me 
down.

The Sony STR-DA5300ES meets criteria (a) and (b) and this approach is 
discussed in this thread

        
http://www.mythtvtalk.com/forum/hardware/7871-biggest-baddest-best-remote-control.html

I used the same hardware.conf (TD-500 specific) and the lircd.conf posted 
in the thread but when I tried it out neither irw nor irrecord detected 
any signal.

Is the receiver in the TD-500 capable of processing the signals from a 
(mimicked) Sony STR-DA5300ES?
Do I need to modify my hardware.conf?


Any help would be much appreciated.

GGGav,
