You save gig ports and its more robust as you can reboot your switch without affecting recordings. With myth controlling the box, there's little reason to keep it on your main network.

In my experience not all GigE switches are equal. I had a no-name
brand GigE switch that would choke once you tried to push any more
than 30MB/s between machines (the only two on the switch). I
replaced that with a 5 port Netgear and could benchmark 100MB/s over
NFS with no other changes. Down the track I started getting
networking issues that appeared to be packet drops under load and
after trying a few NIC changes was about to blame my home cabling
job until I thought to take the switch out of the mix. Somehow the
switch was dropping packets but being unmanaged I had no stats to
tell me that other than what appeared on the hosts.<br>
<br>
TL;DR - buy a decent quality switch, managed if you can afford it.<br>

its own network which was connected to the backend, it solved all
the issues. Maybe it was luck with the fixes in 0.25/fixes coming
at the same time? I have no idea. However, i did some issues
that people reported with the HD homeruns and networking stuff
awhile back also.

Hi, I've seen a few threads on this in the past.
<div>I have 0.25-fixes. I have random HDHR fails.</div>
<div>I have found the only way to fix them is to go
into the setup cards advanced tab and change the
number of tuners from 1-2 or from 2-1.</div>
<div>I headed here after seeing the log error
mentioned multiplexing.</div>
<div>It seems to toggle back and forth which setting
will work and I've yet to see the pattern.</div>
<div>Thought this might save someone some time until
the issue is fixed.</div>

<div>Sounds like your talking about the HDHR prime. If
that's the case then yes, you cannot use multiplexes
when using a cable card. If your using QAM, or ATSC (on
a non-prime HDHR) then you can set this as high as you
think your system will handle/need. I have each tuner
in my 1st Gen HDHR set to 4 virtual tuners as my cable
provider puts all my favorite QAM channels on the same
multiplex.</div>
