<div class=""><p class="">Hello,</p><p class="">I was reading a post of yours from August in a mythtv mailing
list. I have two HDHR dual-tuner boxes like you mentioned but one
of mine is a slightly older HDHR3-US. Therefore in mythtv I've
configured 4 physical tuners. You mention going back afterwards
and adding more multirec virtual tuners. I am assuming that only
my newer HDHR4-US is capable of this but maybe they both are.<br class=""></p></div></div></blockquote><div><br class=""></div><div>Your HDHR3 tuners are able to do virtual tuners as well as the new HDHR4.</div><div><br class=""></div>When you go into mythtv-setup, the additional virtual tuners are defined in the following menu tree:</div><div><br class=""></div><div>Input connections. You will need to step thru each of the 4 connections you would have for your defined tuners. </div><div> Select them one at a time.</div><div> Interactions between inputs at the bottom of the list of choices.</div><div> Max Recordings, I have mine currently set to 4. You can set however many you want. This effectively gives 16 virtual tuners total for the 4 hdhr real tuners. We do have real channels in our area that have up to 8 virtual channels and on channel that has 1 1080i, 2 720p, and 2 480i virtual channels.</div><div><br class=""></div><div>I seem to recall that there is a limit of 5 virtual channels that can be recorded by mythtv tho.</div><div><blockquote type="cite" class=""><div class=""><div class=""><p class="">
</p><p class="">If you can answer a couple questions I'd appreciate it greatly.</p>
<ol class="">
<li class="">What tuner card "type" do I choose when I'm adding the
multirec tuner? HD Homerun again? </li></ol></div></div></blockquote>Doesn’t matter, you aren’t adding additional homeruns<br class=""><blockquote type="cite" class=""><div class=""><div class=""><ol class="" start="2">
<li class="">Once they're all defined do changes to scheduling priorities
then need to be made? Which changes?</li></ol></div></div></blockquote>Nothing I know of.<br class=""><blockquote type="cite" class=""><div class=""><div class=""><ol class="" start="2">
</ol><p class="">I think the multirec tuners only benefit someone who would be
tuning two channels at the same time that happen to be both
included on the same multiplex. Am I correct in this thinking?</p><div class=""><br class=""></div></div></div></blockquote>Doesn’t matter, all the virtual tuners are constricted by the 20( or so ) mbps that can be ’streamed over the air on ATSC 1.0 . The HDHR tuners are just dumping that data when asked as far as I understand.</div><div><br class=""></div><div>There are others in the mailing list that can give better details if wanted.</div><div><br class=""></div><div>I replied to the mailing list as this is good information for the list.</div><div><br class=""></div><div><br class=""></div><br class=""></body></html>
