<div dir="ltr">I&#39;ve upgraded from mythbuntu 11.04 to 11.10.<br><br>Since the upgrade, I&#39;m experiencing the following problem:<br><br>After
 reboot, it is impossible to watch live TV(DVB-T, using a hauppauge 
HVR-1700 pci-e card). Mythtv simply can&#39;t get a signal lock.<br>
<br>running dmesg shows the following:<br><br>...<br>...<br>...<br>[26420.956502] tda10048_set_if() no default<br>[26420.956509] tda10048_set_bandwidth() invalid bandwidth<br>[26420.957324] tda18271_set_params: [1-0060|M] bandwidth not set!<br>

<br>However, if I stop the backend, run tzap on one of my channels 
(using a channels.conf file), and then start the backend, the problem is
 fixed.<br><br>Why do I get these errors? Does anyone know how to solve this issue?<br>
<br>Signal quality is excellent, so this is not the issue.<br><br><br>Thanks,<br>Idan</div>
