I've looked at my unraid server and run in the terminal the command nfsstat and it shows server version as NFS V3. I've done some searching and came across various articles and V4 is does seem to be the default version to use as seen in the nfsmount.conf on the server [extract]:
[ NFSMount_Global_Options ]
# This statically named section defines global mount
# options that can be applied on all NFS mount.
#
# Protocol Version [3,4]
# This defines the default protocol version which will
# be used to start the negotiation with the server.
# limetech - start negotiation with v4
#Defaultvers=3
Defaultvers=4
#
# Setting this option makes it mandatory the server supports the
# given version. The mount will fail if the given version is
# not support by the server.
# limetech - support v4
# Nfsvers=4
I don't know if this file has to be altered where Nfsvers=4 to uncomment it. The majority of this conf file is commented out which I find a bit confusing.
Also my media shares are exported by SMB as well as NFS. I'm not sure if this makes any difference to the NFS version used. I've only updated to this latest version of Unraid on Sunday morning so it has had a reboot. I've also just stopped the array and restarted it to see if the NFS version changes but is stays at V3. I created a new test share and exported it as NFS only but it still seems to use V3. I'm not sure what I can do to make everything V4 unless I need to delete all NFS exports and then redo them all fresh.
I also looked around for information on the broken pipe on sound. To me this seems as if it should be related to actual sound output, but at this time (14:31) of the recording the TV and AVR where powered down from about 13:00. I'm not sure what to make of this.
The recording itself started at 12:03 to 14:08 then the second part of the film was 14:08 to 16:23 (the odd minutes will be padding to start and end). So the first error must have happened 51 mins in (first of the 5 files) so about 12.54.
Looking at the log file myself I see this:
2024-03-31 12:04:00.034 T:989 debug <general>: AddOnLog: pvr.hts: recording id:13092243, state:recording, title:Ben Hur, error:n/a
2024-03-31 12:56:16.091 T:989 debug <general>: AddOnLog: pvr.hts: recording id:2099750975, state:scheduled, title:Ben Hur, error:n/a
I think this entry at 12:56 must have been when I was checking on the recording in the TV Guide and noticed it was actually only recording the first part so I scheduled the second part to record as I hadn't noticed the short programme breaking up the film into 2 parts.
I've looked at the log file myself and it seems like there is a lot going on and too difficult for me to understand.

I'm also wondering if asynchronous epg might be an issue?
