have you enabled "Fast tuning"? I see similar problem, but after disable 
the fast tuning it looks ok (tested for two days).

check the output of:
# lsof -c mythbackend |grep adapter|awk '{print $9}'|sort|uniq -c
     13 /dev/dvb/adapter3/demux0
      1 /dev/dvb/adapter3/dvr0
      1 /dev/dvb/adapter3/frontend0
     16 /dev/dvb/adapter4/demux0
      1 /dev/dvb/adapter4/dvr0
      1 /dev/dvb/adapter4/frontend0
      1 /dev/dvb/adapter5/frontend0


above is ok, i've seen more then 30 for a single demux device and i 
don't think there was a program which has more then 30 streams in his 
PMT.

You can run the backend with -v record to check open and close of PID 
filters.

msc
