Hi,
Many thanks for replying.
Yes to extracting the file to create the .ISO which was then burnt to the disc.
Yes to naming the CD BDPV-11620. Also tried with a DVD (and now have 3 copies!).
I used Vista 32-bit Windows Explorer to burn the CD and the DVD.
I wondered if I should try an earlier firmware update before going with this latest one. Only problem is that I can't find one despite extensive searching.
Any assistance gratefully received.
