TLDR; Why would the HTSP connection interfere with the recording connection?

I'm not sure if this is a bug, or a random glitch.

Recording multiple shows at the same time works fine, but when I try to view one, even if it isn't one of the ones currently recording, I start getting lots of "Continuity Errors". I'm not sure if this is expected for my setup. I wasn't expecting it. I think they are ethernet packets getting dropped errors, but it didn't look like I was saturating my 100mb link.

Ascii diagram of network setup:

                       \-----------------/

Or ignoring the LAN:

+------+       +--------------+      +-----------+
|      >----------------------------->           |
| NAS  |       |  TVHeadEnd   |      |   Kodi    |
|      <----------+           |      |           |
+------+       +--|-----------+      +-----------+
                  |
                  |
      +-----------^--+
      | NetworkTuner |
      +--------------+

I mount the NAS in fstab, and record to that. The idea was that Kodi would pick it up too, and I wouldn't have to stress the really 10 year old computer. Kodi doesn't auto refresh network shares well, so I haven't been using that. I've just been using the PVR client. The network streams should add up to well under 100mb/s.

I tried recording one stream while viewing one other. gnome-system-monitor showed up as about 1.5MiB/s up and down, peaks not going over 2.5MiB/s. It also goes up and down, not pegged at a value as if it were saturated. TVheadend Status shows 2648kb/s in, 2648kb/s out for the recording, and 11534kb/s in 11534kb/s out for the viewing. That's about 13mb/s each way, or if i divide by 8, 1.5MB/s. So that checks out.

I've installed a second 100mb Ethernet card (Netgear), and more storage (I don't use the storage), and the problem hasn't happened since. I'm not sure if it was just a reboot fix or if it is actually using the extra network card. Since it went away, it can't be a "Pentium4" problem, or a NAS problem.
