[mythtv-users] HVR-1600 issue

[Chris Porter]

I recently upgraded from Kernel 3.10.17 to 4.1.13 and I have encountered an
issue recording analog. When on the kernel 4.1.13 I get the following
errors in the MythTV backend log

However, when I switch back to 3.10.17 it works normally.

The problem seems to stem around the attempt to disable streaming which
does not appear to happen when on the 3.10.17 kernel. Has anyone see this
issue and if so have they found a work around?
