<div>Dear all,<br><br>I am trying to record some HD content with a view to eventually getting it to play back somehow. I have got the HD channels within myth but cant seem to record from it, the recording appears to go fine with no errors but the file is 0kb. Has others experienced this and do other people have this working. I appear to be able to get the stream from dvbstream though havent been able to play it back yet. I have a Nova-t and avermedia 771 cards. Any help / other views would be greatly appreciated.
</div></blockquote><div><br>Just to add some more information.<br><br>I can record all SD channels fine and that all works perfectly. I can capture the ts stream by using tzap on bbc hd in a channels.conf file and play it with mplayer (although not played back well).
<br><br><br> BBC HD1:554000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_2_3:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:36932<br>BBC HD2:554167000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE:0:0:36932
<br><br>Note:I do get two bbc hd channels in the channels.conf<br><br>I then record from one<br>tamora ~ # tzap -c ./channels.conf "BBC HD1"<br>using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'<br>

This produces a watchable video (audio bit off). sorry dont have mplayer output but not necessary i dont think, the pids are video 1502 and audio 1505 respectively.
<br><br>I presume that the setup from the channel scan within myth is wrong somehow (this was taken from a recent svn ~10640). The entries put in the database for the channel are:<br><br>mysql> SELECT * FROM channel WHERE name="BBC HD1";
