Fix pid on one channel

NBC (KNTV) changed their equipment. PID changed and showing weather info instead of NBC.

Need to change serviceid.

mysql> select * from channel where callsign like '%KNTV%';

Current (bad) serviceid is '4'. Must hack and try 1,2,3,5.

Try 3 first cuz most of my channels are svcid=3 and stupid NBC Weather stream is '4':

mysql> UPDATE channel set serviceid=3 WHERE chanid='1039';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

Record something. WORKS! :)
Fixed.
