Apologies for taking a while to get back on this, but I've been too busy at 
work.

OK..... theres a flag in the driver which prevents tda10045h_init() being 
called more than once. The only time this is reset is if the upper layers of 
DVB tuning code resets the tda10045h with FE_RESET. I'll have a look into 
this issue.
