I believe you’ll need to allow two programs:
1- “Digital TV Tuner device registration application” (%SystemRoot%ehomeehPrivJob.eve)
2- “Host Process for Windows Services” (%SystemRoot%System32svchost.exe)
And the below ports
– Incoming UDP: 5001-5006, 1900
– Outgoing UDP: 5757-5772, 1900
– Incoming TCP: 2869
– Outgoing TCP: 2869, 554
If you have need tuning adapters then you may need to allow additional ones.
For most users I recommend sticking with the native firewall and Microsoft Security Essentials.
