Elgato used to I believe resell a version of the SiliconDust network DVB-T tuner. Recently I bought a HDHR4-2DT model SiliconDust tuner as the only way to get DVB-T2 on a Mac since for years Elgato had failed to release any DVB-T2 tuners. Update I see Geniatech now list a USB DVB-T2 tuner but still do not have a network DVB-T2 tuner. The EyeTV software does sill support HDHomeRun tuners and I can successfully get EyeTV to find it and can also get it to successfully get EyeTV to scan for channels, and also to view both DVB-T standard definition channels and DVB-T2 high definition channels. Unfortunately I am finding three old bugs specific to using a HDHomeRun tuner with EyeTV still exist. I first encountered these bugs with an older HDHR3-DT model which is DVB-T only. With the recent discontinuation of the previously free RadioTimes XMLTV guide source on June 16th 2016 these bugs have now become more critical as I now have to use the DVB guide instead. I have reported these issues to Geniatech a week ago but as of yet still had no response. I am using the latest 20150826 firmware and software for the HDHomeRun. Bug 1 When I tell EyeTV 3.6.9 build 7416 to use the DVB guide data for channels and to then scan for DVB guide data it will initially start off successfully scanning but part way through will stop finding guide data with the result at the end of the scan only some of the channels will show guide data. I have proven that all the channels do have DVB guide data available by doing the same thing in Windows using the exact same HDHomeRun tuner and this finds DVB guide data for all channels with no problems, and also a real TV fitted with its own DVB-T/T2 tuner is also able to get DVB guide data for all channels. More importantly I can even successfully get DVB guide data for all channels in EyeTV if I tune in to an view individual channels for a few minutes - long enough for EyeTV to extract DVB guide data automatically from that channels/multiplex. If I do this for all the channels missed out during the full scan I can get a full set of DVB guide data for all channels but obviously this is extremely tedious and time consuming and should not be necessary. It seems the failure of the full scan for DVB guide data fails at the same point each time and this seems to be when EyeTV switches from scanning one channel or multiplex to another. However remember it is possible to get DVB guide data for all channels by manually tuning in to and viewing them so it is not as simple as a specific channel causing EyeTV to choke. Bug 2 Once EyeTV has been told to do a full DVB guide data update and it as per bug 1 fails part way through, a subsequent DVB Guide update request will fail straight away as will a 3rd, 4th, etc. It is only possible to then get even a partial scan to work by quitting and relaunching EyeTV. Note: This would further support the case that it is not simply EyeTV choking on the results of a DVB guide scan from a specific channel since a repeat request starts from the first channel which on the 1st attempt does at least give some results. Bug 3 If EyeTV is not used i.e. not running for an indeterminate amount of time - more than a few minutes per a few hours, then EyeTV will no longer reconnect to the network tuner. It then becomes necessary to re-run the EyeTV Setup Assistant and reselect the network tuner. Fortunately you do not have to re-scan for channels. All three of these issues have previously also occurred with older versions of EyeTV, and both a HDHR4-2DT and an older HDHR3-DT tuner and also older versions of the HDHomeRun firmware and software. On the good news front EyeTV is able to extract DVB guide data for DVB-T2 high definition channels which at least in the UK using the Freeview HD service are apparently encrypted with a simple Huffman encoding.
