Is there any way to burn xvid files using nero7
Shouldn't be a problem.
NeroVision will convert to DVD movie format & do quite a reasonable job of it.
With a Divx compatible DVD player you just need to create a data disc.
I tried to use nero vision and burning rom but neither would accept the xvid files. There is no xvid in 'supported formats' in the open dialogue box and even when I set it to '*' it still wouldn't accept them. I eventually burned them with Divx2DVD.
