I've tried various USB sticks, reformatted them with Bootice and finally found one (Kingston) that started to load on booting the H - but only a series of incrementing numbers preceded by an R appeared, rather than a P as suggested in the Readme. They cycled round in three groups up to 100 with EH-C appearing after about each 30 but no progress bar appeared on the TV. Is it just a question of buying/trying more USB sticks? Advice please.
