Windows XP will format a dvd-ram disc as FAT32.
I prefer UDF, which needs a formatting tool - available on the 'Net. Although mine came with my LG 4040, and works with my OEM LG 4120.
I use dvd-ram on a regular basis to back up my data.
Also, my Panasonic E-100 records to dvd-ram, which I can author on my PC.
