Okay, got it going.
FYI... single works, never changed to ocs-dp. What was needed, in addition to the desiqc changes you provided, was more power. After putting a power inserter on the line, I re-scanned 110 and got signal. 119 is still re-scanning now, but I can see there's a vast difference in what I'll be getting. Apparently the Dreamlink T5 provides less power back to the LNB than what I had been using.
Thank you!
