<div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I had problems with scanning channels as well. I had to actually scan<br>
the channels outside of mythtv, and then manually add the channels (I<br>
believe, I did this in April, so I don't recall exactly the steps)<br>
with their listed frequencies. Once I did this, they all worked fine.<br>
Maybe someone else who is more familiar with the procedure could assist.<br>

I ran "scan /atsc/us-ATSC-center-frequencies-8VSB". But the scan utility just says: <br>
<br>tune to: 201028615:8VSB (tuning failed)<br>WARNING: >>> turing failed!!!<br><br>It repeats this for each channel it tries to tune.<br><br><br>
