Kelly,

Those of us who are doing High Def can definitely identify.  There's a 
challenge around every corner.  With regards to the start up issue, I 
noticed the same thing, I think it's related to a delay in the loading 
of the cx88_dvb driver.  I put the following (*total hack alert*) in my 
/etc/rc.d/rc.local:

modprobe cx88_dvb
i=$((0))
while [ $i -lt 5 ]
do
   if RETVAL=`lsmod | grep cx88_dvb`
      then service mythbackend start
      ERR=`tail /var/log/mythtv/mythbackend.log | grep ERROR`
      n=$((0))
      while [ "$ERR" != "" ]
      do
         n=$(($n+1))
         sleep 7
         service mythbackend restart
         ERR=`tail /var/log/mythtv/mythbackend.log | grep ERROR`
         if [ $n -eq 2 ] ; then
            ERR=""
         fi
      done
      i=$((5))
   else
      i=$(($i+1))
      echo "waiting for cx88_dvb to load"
   sleep 2
   fi
done
