Nero 6.6 file burning order (ISO DVD)



Hi, I’m using Nero (previously 5.5) and I’ve recently noticed that I can’t seem to control the burning order in ISO DVDs no matter what: it doesn’t strictly follow Joliet names alphabetical sorting (as showed by Nero browser). Then I thought maybe ISO names were sorted, but it seems it’s not the case. Is it voodoo?
Please, can someone enlight me on that matter (or point me to a relevant thread, I haven’t found a definite answer searching) ?
Thank you
