Only thing I will say... Please join us in the 21st century...
And I am not refering to Windows Me.
Its bad enough 9x has the worst tcp/ip stack (its a hack of NT4 RAS thats been patched a dozen times). And if you're using it and thus stuck w/ fat32, then you shouldn't be dealing with DVD media anyway.
On the flip side, though, DVD-r scene releases are in .iso format, BUT they are then rar'd and broken into usually 50mb files.
