I also have a DN 4900 receiver that I have been trying to get to work with the USbUIRT. I'm going to ask a few noob questions here so bear with me.
1. Do I point the USBUIRT at the sensor on my DN receiver or do I point it at the seating area where I will be using the remote?
2. Do I need to install Grinder or some other medium software to make the USBUIRT work properly?
3. Is there any free software out there that I can use with my USBUIRT other than Grinder?
4. How do I have the USBUIRT learn remote keys?
Last thing..... Can someone help me through the install so that I can start using my system. That would be greatly appreciated.
Thanks a bunch!!
