</div></div>Adding "-v record" to the mythbackend command line is a start. But<br>
you probably also need to be looking at kern.log and syslog for errors<br>
about the drivers.<br>
<br>
Do the tuners work again if you cold start the SBE box (power it down<br>
and leave it off long enough for all the power supply capacitors to<br>
drain, 60 seconds or so)?<br>
<br>
What sort of tuners are these?<br>
<br>
Have you checked the cables? Cables are always the most likely thing<br>
to cause problems.<br>
