i'd go against what others have said;<br><br>yes to 2 signal group thingies (1 for the dvb-t2, and another for dvb-t), but i'd keep all channels if they are duplicate. it just means that you'll have the ability to watch things should one of the tuners be in use.<br>
<br>there is a guide on scripting the channels (<a href="http://www.mythtv.org/wiki/UK_Channel_Assignments">http://www.mythtv.org/wiki/UK_Channel_Assignments</a>).<br>i do this for DVB-S2 and DVB-T channels - completely different signal sources but i have the option to use either card for channels that are broadcast on both systems (eg BBC1).<br>
i cant remember what determines the same channel - i think it's the channel name.<br><br>as for scheduling, you could set the DVB-T tuner to +2 priority, but have HD shows with a +4 priority. obviously the higher the priority, then it will record on that tuner.<br>
<br><br>hope that helps..<br>
