[mythtv-users] How to record from a specific source ?

[lanas]

Folks,

  I have two inputs on the PVR500.  One from digital cable (i.e.
channel 3, composite input), the other from straight cable.  I want to
manually set a recording time for the composite input. but there seems
to be no such option but a choice of channels.  Is it possible at all ?

Thanks,

Al
