ZoneAlarm security message

I just installed the free ZoneAlarm firewall. Every few minutes (sometimes every few seconds) I keep getting a security message that says "The firewall has blocked Internet access to your computer (NetBIOS Name) from 192.168.1.2 (UDP Port 3334)." By Googling port 3334, it looks like it has something to do wiht DirecTV. WTF??? And 192.168.1.2 is my router. So what could be causing this message? Also, how do I open a port in ZA? I looked at the help file, but the instructions do not seem to jive with the options available in the program.

I have attached an image of the security message.

Thanks for any help.

 

DO you have a TIVO box on your DSL line.... thats the only thing I can think of.

 

Nope.
