I had a funny experience with NeroLinux. I burnt a DVD with two files, one of them is just a couple of bytes, the other one was more than 4 GB. The burn was succesfull (according to Nero) and the verification was OK. But when I mounted the DVD, the big file was shown to be about 300 MB.
It took me a bit of time, a couple of web searches, and another unsucceful burn to figure out, that ISO9660 doesn’t support files larger than 4 GB. So I found my explanation, but I think Nero should at least warn you about this, instead of claiming that your burn went fine.
Otherwise I like the software, if I don’t find any flaws by the end of the evaluation period, I’ll buy it.
