After running the black hole image I have found a bug in it.
Selecting - menu/setup/service searching/positioner setup/
This causes a crash and enigma reboots - however it's easy to fix!
open the file
/usr/lib/enigma2/python/Components/TunerInfo.py
then go to line 63 and do this:
change this - if value != 0x12345678:
to this - if value is not None and value != 0x12345678:
Upload the file back to your box and restart enigma - your crashes will be over......
