When I try to convert an xvid file to dvd using Nero Vision, everything starts off fine. Under video options I have everything set to automatic and automatic (fit to disc). The "Total space used bar" says Im using 4.37 out of 4.38gbs. Yet when the encoding is finished and the burning starts it tells me that the disc isn't big enough. Ive tried two separate xvids and I get the same error. Also, why does Nero Vision say 4.37gb out of 4.38gb when my blank DVD's hold 4.7gb? I even tried enabling overburn, but that just resulted in an "Invalid command" error right when burning started. Ive used older versions of Nero Vision in the past and have never experienced this problem. Any help would be greatly appreciated.
