[mythtv-users] Upgrade from 0.26 to 0.27 broke firewire

[Peter Bennett]

I have struggled with the firewire issue - megabytes of "no input in xxxx msec" in the log and no recording. It seems to be random as to when it happens. I had it consistently for 6 months then it stopped. That was with mythtv 0.24. It stopped for a year or so then started again on mythtv 0.26. At that time somebody on this forum recommended changing to a firewire card with Intel chipset instead of VIA chipset. Evidently there was a bug in the firewire Linux driver for that chipset. Since I changed to a card with Intel it has not happened. 
My fix for when this happens is a script that restarts the backend. If you kill and restart the backend, it picks up the recording again and does not have that error again in that recording. (sudo restart mythtv-backend in Ubuntu). 
My script continuously monitors the log file and kills the backend when those errors happen for a couple of seconds. Very little recording is lost but the recording is split into two files. 
Look here for my scripts

The monitor script is here
