Also, and perhaps unrelated, is the fact that the card has 4 tuners (2<br>
analog and 2 digital) but MythTV always says it has 6. I set up all 4<br>
tuners in mythtv-setup, it only shows the 4 tuners, but when I try to exit<br>
mythtv-setup it tells me that the starting channel for tuners 5 and 6 are<br>
"Please select ...". But those tuners aren't there! "Tuner Status" in the<br>
MythTV frontend also shows 6 tuners. I have deleted and re-added all of<br>
the tuners over and over again. Any thoughts on that will be most<br>
welcomed, too.<br>

This could just be the fact that digital tuners can do multirec. You have two physical tuners, but the system default is to allow two virtual tuners from each physical one.<br>
<br>
If you want to get rid of those to avoid confusion, I think it is on the second page of tuner definition in mythtv-setup. However, it won't harm you and is even useful for recording back-to-back programs from the same channel with overlap.<span><font color="#888888"><br>

Hmm, IIRC multirec use the same starting channel number. likely something else.<br></div></div><br></div></div>
