Burned the 2.3 iso to a cd tonight using Nero burning ROM. Burned it at 12x speed and my HD-A1 player had no problem reading it. Upgrade took about 10 minutes I'd reckon (Was outside grilling at the time, so can't be sure of exact time). That's my first attempt at upgrading via a burned disk and it went swimmingly. I guess I must be a natural
I timed the boot process and it seems to take roughly as long as the firmware 2.2 boot times I noted last time I upgraded my player, so no improvement there.
Does anyone know what this firmware actually fixes?
