LIRC config file/channel chg script for SA Explorer 2000, Hauppauge PVR 150 w/ IR Blaster?

Can anyone recommend or offer a working LIRC file and channel change script available for using with the following hardware: SA Explorer 2000 + Hauppauge PVR 150 w/ built-in IR Blaster and remote? The Hauppauge tuner card is the PVR 150 (1047 kit) with the IR Blaster (Transmitter and Receiver in one). On the back of the remote in the battery compartment is the code A415-HPG. I believe this is the so-called 'new grey remote.' The set top box is a Scientific Atlanta Explorer 2000. I know the code for the SA Explorer 2000 is 78. Or 0078 (the same thing?). But, I am hoping someone who has the same set up or hardware will read this post and offer the channel_change.sh script and LIRC/irblaster config file they used and got to work.

It would be ideal if it worked with the most recent, up-to-date KnoppMyth Mythtv version.

(Also, if by some miracle, I am able to obtain them, I could post them if anyone thinks it's a good idea). Also, if you've seen a post with this info and have the link, I would greatly appreciate the info.

Thanks in advance.
