Had a fault with my arcam dv27 dvd player (Internal fuse blown twice) whilst on the phone to the help desk i inquired about upgrading the firmware from 1.79 to 1.81. They sent out two firmware disks (1 for firmware other for sil chips i think) equiped with detailed instructions. I tried installing the firmware disk and the player tried reading it but after a few seconds failed and came up with -bad disk- The other disc read and installed fine? Any reason for this? No damage is done and on start up the player reads 1.81 but its just bugging me why the disk labelled firmware wouldnt install/read.
