Detailed Description

The Program Association Table lists all the programs in a stream, and is alwyas found on PID 0.

Based on info in this table and the ProgramMapTable for the program we are interested in we should be able determine which PID to write to the ringbuffer when given the program stream to record.

NOTE: Broadcasters are encouraged to keep the subprogram:PID mapping constant. If we store this data in the channel database, we can branch-predict which PIDs we are looking for, and can thus "tune" the subprogram more quickly.
