Derived cDevice classes that can receive channels will have to provide Transport Stream (TS) packets one at a time.
cTSBuffer implements a simple buffer that allows the device to read a larger amount of data from the driver with each call to Read(), thus avoiding the overhead of getting each TS packet separately from the driver. It also makes sure the returned data points to a TS packet and automatically re-synchronizes after broken packets.

A derived cThread class must implement the code it wants to execute as a separate thread in this function.
If this is a loop, it must check Running() repeatedly to see whether it's time to stop.
Implements cThread.
