Nothing has changed with that setting and the PVR-x50 type encoders.  If 
you've selected the proper tuner type ("Analog to MPEG-2 encoder card 
(PVR-150/250/350, etc)"), you should see:

Preset tuner to channel
Leave this blank unless you have an external tuner that is connected to 
the tuner input of your card. If so, you will need to specify the preset 
channel for the signal (normally 3 or 4).
