Hi,

Did you try drag&dropping the MPEG file right onto NVDVD?
How does your file look?

I'll find out about how to tell if you're using the NVDVD codec.
Windows doesn't have a nice way to handle codec
conflicts. I had a situation in which an MPEG2 decoder had
inserted itself before the NVDVD decoder, so NVDVD would use
the other decoder.
