Any dvdburner is good as long as you stick with
the manufacturer's suggested blank dvd brand.
The better popular burners are Sony and Toshiba.
Get one that reads/writes at higher speeds.
First, you need to convert the .wmv file to .mpeg
(try "Arcsoft ShowBiz"...it came bundled with my dvdburner)
The reason to convert to .mpeg is because mpegs are
dvd-compliant.
Once converted, Arcsoft Showbiz will allow you to burn
your movie to dvd (my version of Showbiz creates
dvd without menus)...
Arcsoft Showbiz DVD, however, creates dvds WITH menus.
(I have this version, too)
Arcsoft Showbiz also converts avi's and some
VOB files (from dvds pre-dating 2001), too.
