Can't start channel on HDHomerun

[westptx]

So I've been having this issue for a couple of weeks on-and-off. Generally, I've just rebooted everything to solve the problem but it continually happens and the wife isn't happy.

The Problem
Seemingly randomly, I cannot access a given channel. There does not appear to be any pattern on what channel doesn't work and most other channels will render, just randomly a channel doesn't render.

My Setup
HDHomerun with Comcast M-Card (3 tuners) plugged directly into our gigabit ethernet
1 Media Server w/ NPVR running 24x7 (wired)
- Live TV buffers to an SSD
- DVR records to a generic JBOD drive
4 XBMC installations at various points in the house (all of which are wired)
- all are using NPVR add-on (not surprising)

What I've Tried
1. Restarted XBMC, waited for EPG to fully load/update and select the problem channel (doesn't work)
2. Changed to a different channel (which does render) and then change back to problem channel (doesn't work)
3. Restarted XBMC + Server + HdHomerun (sometimes works, sometimes doesn't)

What I've Been Able to Find
1. It doesn't appear to be the HDHomeRun. Manually opening the channel (across all 3 tuners) in VLC works fine. I've never had an issue opening a stream to a channel directly on the HDHomeRun when these instances occur
2. I can see NPVR creating .ts file in the buffer location (e.g. live-TLCHD-1596-2.ts), however it is a relatively small file at 2,718 KB and doesn't seem to increase (broken stream?)
3. When this issue occurs, it occurs everywhere and on all machines. It's not isolated to any one XBMC box.


I've attempted to provide the cleanest log possible so I cleared out the logs and then repro-ed the issue. Hopefully the logs (attached) capture what's going on. It seems like NPVR was able to get the stream cleanly but, for some reason, wasn't able to come through in XBMC
