[mythtv] Ticket #2762: Missing define for "dvb_fe_caps_extended extinfo" in libmythtv/dvbchannel.h

[Mark Buechler]

Compile failure attached. The dvb version I'm using is mercurial as of June
23 2006 with the necessary DVB-S2/8PSK patches installed. Those patches I've
attached to the ticket. I can provide the tree if you need it but I think
it's something really simple and overlooked when several methods were split
out into DTVChannel.

The patch for the extinfo define is simply (patch attached):

--- dvbchannel.h.orig   2006-12-02 17:42:41.000000000 -0500
+++ dvbchannel.h        2006-12-02 16:07:18.000000000 -0500
@@ -101,6 +101,9 @@ class DVBChannel : public DTVChannel
     DTVMultiplex      desired_tuning;
     /// Last tuning options Tune() succesfully sent to hardware
     DTVMultiplex      prev_tuning;
+#ifdef FE_GET_EXTENDED_INFO
+    dvb_fe_caps_extended extinfo;  ///< Additional info on tuning hardware
+#endif

     uint              tuning_delay;///< Extra delay to add for broken
drivers
     uint              sigmon_delay;///< Minimum delay between FE_LOCK
checks

But it looks like to me you probably want that defined in
dvbchannel.cpprather than the header since the normal frontend info
define is there as
well.

The first bt I attached was after the above patch was applied. I tested
several times, everytime a segfault in the same place. The second bt is with
QMutexLocker commented out in DTVChannel::SetSiStandard().

Hope this help.
