Hi Per,

Using more than 8 DVB devices:
------------------------------

I usually, Download V4L from 
http://mercurial.intuxication.org/hg/s2-liplianin,

Run an initial make (this creates the v4l/.myconfig file)

CONFIG_DVB_MAX_ADAPTERS = 8
  to
CONFIG_DVB_MAX_ADAPTERS = 12 in the private config file

re-run make && make install


Using more than 5 tuners/recordings per device in MythTV.
---------------------------------------------------------

It does seem strange that MythTV limits tuners per device when some 
MUXes can have up to
  20 channels on them?, anyway to change this,

Update "Max recordings value from 5 to 20"

mythtv-0.xx/mythtv/libs/libmythtv/videosource.cpp

class InstanceCount : public TransSpinBoxSetting
{
   public:
     InstanceCount(const CaptureCard &parent) : TransSpinBoxSetting(1, 
5, 1) <-----Change 5 to 20
     {
         setLabel(QObject::tr("Max recordings"));
         setHelpText(
             QObject::tr(
                 "Maximum number of simultaneous recordings this device "
                 "should make. Some digital transmitters transmit multiple "
                 "programs on a multiplex, if this is set to a value 
greater "
                 "than one MythTV can sometimes take advantage of this."));
         uint cnt = parent.GetInstanceCount();
         cnt = (!cnt) ? kDefaultMultirecCount : ((cnt < 1) ? 1 : cnt);
         setValue(cnt);
     };
};



In my case my front-end has 24G of RAM and 10G Infiniband for storage 
from the front-end to the back end  so I can handle the potential of 
recording 240 channels at once :).

One last note, the above settings are changed from mythtv-setup program, 
when setting up the DVB device.
