Re the Full/High/Low thing, that is in the power scan, Symbol range, and with the Ultra, if you do a power scan, the "full" setting doesn't work very well. I do scans both in high and low. If you know what the SR value is, you can select the appropriate one, ie since you know it 6149, use the low setting if you're doing a power scan.

Re the 13V vs 18V, the fortec uses an lnb voltage of 13V for one polarity, and 18V for the other polarity (I can't remember which is which. And since your ULTRA is powering an LNB which prefers 18V, you should try to use the appropriate polarity, regardless of which polarity the signal actually is, because your 4DTV is controlling the polarity.

Re the DC-block, I'd put that between the Fortec and the 4DTV, just to protect the Ultra from the external power source. Your Ultra will be providing power to the LNB, since the DC block isn't between the ULTRA and the LNB. The DC block may not be absolutely necessary, but it is safer to use it.
