Thanks
nipbiplip, I have tried the hack but my telly still displays 480p in the top left hand corner when I switch to it so I don't think it works. I must have a 2006 model and therefore why it doesnt work.
I would use HDMI but have an expensive component cable (which can be returned) but also have to consider that Sky HD is arriving in August.
The firmware downgrade and switch could be a possibility but would invalidate my warranty, but I do have a Richer Sounds extended warranty.
Thanks for thip for the PM!
