bug in current (free) version?

[Guest]

hi, I created a file which size is 4697620480 bytes and I tried to burn it using deepburner.
At first I was surprised because the time to burn toke just 1:30 minutes. After I had took a look at my dvd I got shocked - deepburner just burned ~300 MB. I am unable to send you the file for tests

What DVD-R/DVD+R are you using?
What for a burner do you have?
