It would be really nice if the HDHRs tagged their packets with
real-time priority in the IP packet DSCP header bits.  Then you could
set up the Ethernet port so that the packets with high priority took
precedence over the standard priority packets and the HDHR traffic
would be able to get through even when the port was being used to full
capacity by other traffic.  Not having an HDHR, I am unable to take a
look at its packets to see what the DSCP bits are set to.  There are
some posts out on the net that suggest that the DSCP bits are set, so
if they are, it would be worthwhile taking a look at what it takes to
enable QoS processing on your Ethernet port - and on your Ethernet
switch also if it supports that.  But before that, someone with an
HDHR needs to run Wireshark or tshark or tcpdump to capture some HDHR
recording packets and confirm the DSCP bits are being set properly.

Don't know if this is helpful or outdated but did a search on HDHomerun and
DSCP and this came up:
