|
|
I am able to watch TV on a newly installed mythtv setup. I am using a HD Homerun ethernet TV tuner. However, I am seeing 1.2MB/s-1.8MB/s usage a couple of minutes after I close the front end. I do not have myhtv setup to record anything. I know it is mythtv beacuse "/etc/init.d/mythbackend stop" stops the network usage.
Is this excessive network usage? I think it is but I am nor sure. Again, nothing is set up to be recorded.
Any comments/suggestion to reduce this network usage when I am not recording or watching would be appreciated.

It seems like a pretty high network usage unless mythtv is running a background task to transcode recordings. |

Finding and marking commercials is also a task that could be off-loaded to networked systems. |

Do you have any other machines running mythbackend? Or just the one combined front/backend?
Have you tried adding "ALL" (just do this temporarily" to MYTH_VERBOSE in /etc/conf.d/mythbackend and then doing
Code: | # tail -f /var/log/mythtv/mythbackend.log | to see what myth says it's doing then? |

Sorry about the delay, I was not getting email updates from theis forum post. The mythtv install all on one machine. I do not think I have done anything special to it (yet)
Here is what i did:
Code: |
/etc/init.d/mythbackend stop
edited /etc/conf.d/mythbackend for "all"
rm /var/log/mythtv/mythbackend.log
/etc/init.d/mythbackend start
waited for the network traffic
/etc/init.d/mythbackend stop
|
It appears to be mostly lines like:

I suspect that the bandwidth is mostly the back end polling for TV directory information. |

It's been a while since I used mythtv for anything besides watching videos, but this looks like your machine is polling the HDHR for EIT schedule information. Do you use the OTA information for your scheduling or do you use something like schedulesdirect? |

I am using over the air information to get the EIT schedule information. |

Then I think that that traffic is the HDHomerun pulling in scheduling information. To check you could disable the EIT on that tuner, and see if that stops the traffic. If that is the case, I don't think there is anything you can do about it. My understanding of EIT is that it trickles in over the course of the day for the next while. The only option I know of to avoid using EIT is to switch to schedulesdirect,
