The fix I mentioned being worked on in my post here has now been released to beta - in version 1.18.8.2527
Release note Plex Media Server - #324 by emilybersin
- (DVR) Channels mapped to two different numbers in a lineup could fail to tune. (#11225)
Please can you now map channel 38.1 back to 38.1 in DVR Settings enabled channels and then upgrade to version 1.18.8.2527 and after launch - do a manual EPG Refresh through DVR Settings and on completion check that 38.1 does appear correctly in the grid and does tune ok.
Please let me know either way and if there is an issue, please get server logs
