I have a home system comprising of four MythTV frontend/backend combo boxes. Three are attached to DCT-6xxx boxes. The fourth uses an HDHomeRun as input. All four boxes are similarly configured running Ubuntu 7.04.<br><br>
Last weekend, in an effort to prepare for a transition to Schedules Direct, I upgraded all of these boxes to the latest SVN version. At the same time, I also upgraded Ubuntu to the latest packages (including the kernel to
2.6.20-16).<br><br>Everything went fine. <br><br>Except now, all of the systems attached to DCT boxes fail to receive video. In MythTV, I cannot tune any channels - and all attempts to record programs fail. <br><br>When I run plugreport, everything looks normal. But firewire_tester reports failure both as a broadcast connection or as a point-to-point connection.
<br><br>I have tried rebooting and loading the old version of the kernel. The results are the same.<br><br>Before the upgrade, all of these boxes worked fine. Now they all fail. Since, I was stupid enough to upgrade the kernel and MythTV at the same time, I really don't know which caused the problem.
<br><br>While it is possible that my cable provider downloaded new software which disabled firewire output at the same time, I think the odds of that are pretty remote.<br><br>I'm looking for some pointers as to how to troubleshoot this. There are no error messages, just a failure to receive output from the DCT boxes. HELP!
<br><br>Thanks.<br><br>Tom<br>
