There were several DVR fixes in 1.32.6.
The release notes for 1.32.8.7639 list one change for LiveTV:
- (LiveTV) Transcoded video would fail to play in some circumstances (#14539)
Go ahead and fall back to a prior release if you want. That would help determine if the problem is only with the current beta release.
The current public release is 1.32.7.7621 and is available at plex.tv.
To fall back, you’ll first have to uninstall 1.32.8, then install the desired version.
When uninstalling, you’ll see an “Are you sure” screen, then a screen with three options. Choose “Uninstall Only.” This keeps everything in the Plex Data Folder intact (database, etc.)…
One the uninstall is finished, install the desired version.
