I don't know of anybody that makes an
hd-dvd burner. LG makes a blu-ray burner,
LG Optical Drives - Model GGW-H20L: for like $400 that will do single layer 25gig blu-ray disks.
Or the
LG Optical Drives - Model GGW-H10NI: player for $1000 that will do 50gig dual layer blu-ray disks.
I have only seen single layer disks for sale so far and they run between $15-$20 each, I'm sure dual layer disks aren't far behind.
