Hello there, I am new to the whole Remote modding and I need help, I have gone through the whole devices list that this website has to offer, looking for the devices that I use on a daily basis, in order to mod my remote to work on my devices. But I was only able to find one device that I own on the device list.
I was wondering if someone can either teach me or point me the right direction in making my own ncf file for each of my devices correctly, or is someone can actually help me find or help me by making me one, if its not too much to ask. If it helps any these are the following devices that I own.

Hitachi - 50v710 rear projection LCD
Yamaha - HTR 5740 Receiver
Dish Network DVR 552 - DBS
Cyberhome 500 which I found in the device list.

The reason I purchased this remote is because I was told that it would copy the same function as the remotes that come with my devices, I was just fed up with having to use 4 different universal remotes for everything. Thanks
