Hi everyone, I have tried without any success to master a DVD on this box. Following advice I found on threads from this site, I upgraded the firmare (from 1414 to 1416). It now at least recognises one of my brands, and even attempts to write to it (which is progress!!). It won't have anything to do with the Maxell DVD-R disks I have (1x - 8x speed). it at least now recognises the TDK 4x DVD-RWs (an improvement from 1414), and attempts to use. Following a burning session though it then tells me that it doesn't recognise the disk in the drive (it just burned the **~~""??!?! thing). None of my other DVD players recognise the results either - its a beer mat! Can anyone assure me that a given brand DOES actually work with this box? I've ordered a random selection of media, which I am expecting any day, but all advice is appreciated. You can't seem to get 1x or 2x blank disks anymore. It has no trouble using the Panasonic DVD-RAM disks that came with it, but that don't help much! Cheers, Doug.
