Possibly the Hauppauge tuner is a dual standard card and you are actually using ATSC?I purchased the UK version of the SiliconDust HDHomerun Quad DVB-T/T2 tuner in December 2025. Disappointingly, it does not work fully with MP. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite4" alt=":mad:" title="Mad    :mad:" loading="lazy" data-shortname=":mad:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite16" alt=":cry:" title="Crying    :cry:" loading="lazy" data-shortname=":cry:" />In the UK, a DVB-T or DVB-T2 MUX is a single UHF frequency that carries multiple digital TV channels that are multiplexed together. The one-and-only DVB-T2 MUX carries 7 high-definition (HD) channels, while the various DVB-T MUXes each carry circa 15 standard-definition (SD) channels.MP can perform the clever trick of receiving and recording multiple channels that reside in a single MUX, and use only one tuner while doing so. To achieve this result, MP asks the HDHomerun to send the entire MUX data stream down the network cable. When I looked at the network activity on the "Performance" tab in Windows "Task Manager", the DVB-T MUX data stream for a single tuner was a consistent 23 Mbits/sec, while the DVB-T2 MUX data stream for a single tuner maxed out at 40 Mbits/sec (it was a bit more variable than the DVB-T data stream).If you reside in a country that has 4 or more DVB-T2 MUXes, the total data stream load would be:<ul> <li data-xf-list-type="ul">4x40 = 160 Mbits/sec for 4 DVB-T2 MUXes</li> <li data-xf-list-type="ul">4x23 = 92 Mbits/sec for 4 DVB-T MUXes.</li> </ul>The problem is that the HDHomerun's network connection is "fast ethernet", i.e. 100 Mbits/sec. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite16" alt=":cry:" title="Crying    :cry:" loading="lazy" data-shortname=":cry:" />I tried recording 4 channels simultaneously, each channel in a different MUX, with one of the channels being an HD channel. "Task Manager" showed the network link constantly around 97-98 Mbits/sec. But the real problem were the thousands of continuity errors in the TV Server log file, indicating a great number of dropped frames, making the recordings unwatchable.So sadly my conclusion is that the HDHomerun is not really a quad tuner. If you have only DVB-T2 MUXes, the HDHomerun is a dual tuner. If you have only DVB-T MUXes, you are very near the limit of the capacity of the network connection, so it might work OK as a quad tuner. Treating the HDHomerun as a triple tuner would give you adequate safety margin for DVB-T MUXes. To address this problem, the HDHomerun needs to have a gigabit network connection, but such a version does not exist at present (and may never exist). I suspect that the HDHomerun was originally designed with Windows Media Center in mind. WMC suffers from the limitation that it requires a separate tuner for each channel, even if those 4 channels all reside in the same MUX. There is a "WMC mode" that results in the data stream for only one channel being sent down the network cable for each tuner. In this mode, a 100 Mbits/sec connection is adequate. But in this mode you lose MP's ability to record multiple channels from the same MUX using only one tuner.Annoyingly the HDHomerun does not allow a static IP address to be defined. This may or may not matter to you (it matters to me). Once you have installed the SiliconDust config software, the setup will download and install the latest microcode for the HDHomerun. MP "TV Server Config" then simply finds it on the network, and you set it up just like a PCI or PCI-E tuner.-- from CyberSimian in the UK</blockquote>
