[X4U] Tiger DVD burning: LAME!

[netkat at comcast.net]

hi, michael;

At the time of one of those errors, I was trying 
to burn 4.11GB of data onto a disk. IIRC, that 
4.74GB size refers to the total space on the 
disc, including the instructions needed to 
navigate and manage the disc.

I've found that I can reliably put 4.25GB of data 
onto a DVD. 4.25 is larger than 4.11, a fact the 
OS and the Mini weren't getting.

I wasn't doing any kind of fancy burning here, 
just load up the data, and hit "burn," resorting 
to creating disk images to get it done (at the 
cost of much time!)

Peripherals:  I have a dongle which I use with 
Lightwave, and a powered USB hub with my 
keyboard/mouse connected to it (dongle takes up 1 
of the Mini's usb ports; the hub another).

I did the trick of creating a new account, and 
burning (successfully) then went back and trashed 
those prefs files.

Have no 3rd-party burning software or any 
utilities for that matter; I reinstalled my 
system Saturday, and haven't even gotten around 
to putting all of my software and utilities back 
on, so, this is a pretty Apple-pure system.

thanks!
