<div>I have an HVR-1600 (borrowed) and an HVR-1250 in my MythTV FE/BE (m2npv-vm 4200+). Plugging the cable into either card allows the backend setup to discover about 80 channels. Only six of these channels (ABC, two CBSs, two PBSs, and Fox) get a signal in Watch TV in the front end. The rest of the channels return either:</div>
<div> </div>
<div>1) Signal 0% | S/N 2.5dB | BE 12998 | (l___) No Lock</div>
<div>
<div>2) Signal 0% | S/N 2.5dB | BE 12998 | (LAMc) Partial Lock</div>
<div> </div>
<div> </div>
<div>- There is no cable box involved</div>
<div>- The HD television picks up all 80 channels plus the analogs as well.</div>
<div>- The digital channels are crisp and clear on the TV</div>
<div> </div>
<div>Q1: What does the 'c' in the partial lock mean? I looked at <a href="http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.22" target="_blank" rel="nofollow"><font color="#0000bb">http://www.mythtv.org/docs/mythtv-HOWTO-23.html#ss23.22</font></a>, but no 'c' is listed as a possibility</div>
<div>Q2: What might be causing my problem?</div>
<div> </div>
<div>Thanks,</div>
