So I moved the cables around so that one of the GbE switches had the HDHR, mythtv backend, and the cable running to the cabinet with a switch for the streaming devices. This seems to fix the issue. However if the cable going to the streaming devices is plugged into the switch above then I have issues.

Sounds like the box and signal is OK by what your describe.</div><div><br></div><div>Recently I had a similar problem where my recordings had breakups/pixelation and my hdhrconfig gui the signal looked fine. I use a wireless bridge to push from the hdhr to my server, with one switch in its path. I separate out my wifi from my router and use a separate dumb ap for wifi. So it is hdhr ethernet to wifi bridge unit (tp-link c7 - openwrt) wireless to belkin3200ax then wired to Netgear gaming switch then wired to backend recorder. I use a programmable netgear gaming switch. Swapping out the ap for the new 3200ax solved my problem and it is perfect again. The shields I use mostly for viewing both are switches that feed from the netgear switch. From what you describe your issue is one of the switches I would guess</div><div><span></span></div><img width="1px" height="1px" alt="" src="http://email.mg.glenb.net/o/eJwlyzsOwyAMANDTlK3IGMxn4DAGm6RSkkokrdTbt1LHNzypfbBQMI-aG3psTjwQSg_OKys0pQgBCpfoXHbogW3nXbdbgGXTo9lDL7PWHGAkEhyAo5C4SIETph5pKCdfzKz751qv9_116jx_-0_7nMsXwuwnnw"></body></html>
