<tt>Hi.<br>
</tt><br>
<tt>I am trying to get DVB-T to work with MythTV here in Norway which also uses H.264 and AAC.<br>
</tt><br>
<tt>Is it necessary with any patches in order to scan and tune these channels in MythTV?<br>
</tt><br>
<tt>scan finds all the channels when I run it and outputs a channels.conf that looks correct.<br>
</tt><tt>tzap can successfully lock to the channels and makes the datastream available.<br>
</tt><tt>If I pipe this datastream to mplayer svn as of yesterday it identifies the stream as mpeg2.<br>
</tt><br>
<tt>If I try to import the channels.conf file into MythTV it will not find any channels, but the signal strength and quality bars indicate quite high values. Trying a full scan with the available frequencies gives the same result.<br>
</tt><br>
<tt>I have tried this with both MythTV trunk r20409 and fixes. Also tried fixes with JYA's latest patch for VDPAU but still no luck.<br>
</tt><br>
<tt>The DVB-T card I am using is a Hauppauge HVR-4000 by the way.<br>
</tt><br>
<tt>I am using OpenSuse 11.0 so any Ubuntu binary packages is out of the question I guess.<br>
