Many people have trouble setting up serial/usb channel changing using DVBLink, DirecTV and Windows 7. I am going to show you the software, hardware and steps I used to get channel changing that is 99% accurate (sometimes it misses the NFL Sunday Ticket HD sub channels).
- HDPVR IrBlaster Bridge – This is a drop in replacement for the Hauppauage IR Blaster DLL. It currently supports talking directly to the DirecTV STB via the serial port.
- (Optional) DirecTV Channel Control v1.0– This is a utility that will allow you to change channels and control your external direcTV set top box using the low speed data connection (home control) port in the back of the receiver. This is only needed for the NFL Sunday Ticket HD
