Playing 8x DVD+R disks

[rfisher]

Just got a DVD recorder to replace my VCR. Can play 4x +R disks after recording on my second DVD player but not 8x. Anyone know why?

Er, take that as a no then. Can't believe I've stumped the entire PH collective.

Thanks. The player is quite old so I may just get a newer one. How do you update the firmware on a DVD player anyway? Does it need to be attached to a computer or do you write the programme to a DVD disk?
