Potential EPG / Tuning Issue

noyodeling · 2021-09-25, 09:48 PM

I've been experiencing a sudden change in channel while I've been watching either via the web UI or via Kodi. While on a channel, it would suddenly switch to a different channel without indicating via the UI. It would keep doing it until I reset the service. I couldn't find a pattern until recently.

I was watching a channel and it changed to a different one around the same time it was scheduled to do an EPG update.

Please see the relevant device logs below. I have a Hauppauge Dual HD USB Tuner. The first <tuning /> block is the channel I was watching when it happened. Any help is appreciated.

Using NextPVR during an EPG update is not recommended. If you are using OTA ATSC and doing frequent scans this can be a problem. Please post your entire zipped logs if you want us to look into it.

Yeah, don't do that.

Ha. Thanks guys. Noted.

I added multiple EPG updates since it was only giving me data for a few hours. I don't remember what it was giving me for sure since it was so long ago. I'm going to set it back to once and day and see how that goes.

Thanks again. Cheers.

Short guide data is a know issue with OTA ATSC you probably won't be happy with once a day. That is why Schedules Direct for a cup of coffee a month is a bargain.

I'll look into it. Thanks!

All setup on SD now. Working great. Thanks guys.
