Andrew,<br>
<br>
First thing that comes to mind is that order of you tuners maybe changing<br>
between reboots.<br>
I presume that you have either used udev rules or an options.conf file in<br>
/etc/modprobe.d<br>
<br>
Please post the result of dmesg|grep -i frontend<br>
<br>
<br>
Mike<br>

<br>
</div></div>Here is the dmesg info you asked for<br>
<br>
....~$ dmesg|grep -i frontend<br>
