In the dvb api, a PES_FILTER is also used to get the raw TS stream for a
pid.  There is anothing about a PES_FILTER that requires the PID to have
PES data on it.

If you setup two filters for the same PID, I think the software filter code
will handle it ok.  For a device with hardware filters, it probably depends
on how the hardware works.
