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.
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
Everything went fine.
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
When I run plugreport, everything looks normal. But firewire_tester reports
failure both as a broadcast connection or as a point-to-point connection.
I have tried rebooting and loading the old version of the kernel. The
results are the same.
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.
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
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!
