Pye PRV 645 - firmware?

Just bought a Pye PRV 645 from my local Asda here in the UK - this is a rebadged Philips 610. Checked the firmware rev and it is the 22/03/2005 version, but on the site there is a new 610 firmware from 26/10/2005. Downloaded and burnt it, but the writer fails to recognise the disk, presumably as it is for a different model. So, the question is, does anyone know how to make it take this update or does anyone have a link to the same update for the Pye?



PRV 645 has it’s web page - no firmware there yet
