I read the threads earlier and it was from those and elsewhere that I built my own ukchan30. It works for me, but I'm not using the RF out (which was one of the other poster's problem I believe...)

I will put the Thompson image on when I get a bigger disk - and I have seen some of the insatbility well documented elsewhere. US image has been good for a test however, and I have learnt a lot about the TiVo :-)

I will try the dbsetx route, but I would assume that if the software hasn't created the setting, it won't expect to read it either.... Though it might make the script not fall over... but iicset seems to segfault for me anyway, so I'm not sure that will get me anywhere.
