this thread is just to show how different drives with varying firmware can make a seemingly bad disk look good with correct writing strategies.

Taiyo Yuden TYG01 DVD-R 4x

media code:

burned with liteon 811 (HSOP fw) at 4x

as you can see not a very good burn for supposidly very good media.

same image and disktype burned with NEC2500A with new stock 1.07 fw.

And yes i burned it at 8x (yes stock 1.07 does burn some 4x disks at 8x!)

Wow difference between night and day!

Caviet: i have not tired the new fw HSOQ for my 811 which may make the above burn somewhat better.

Nice looking scan @ 8x for TY -R…I’m going 1.07 now, you convinced me.

Works very well…this is a Fuji Branded 4x, 4.3gb burned at 8x. You can see where the drive burned at 6x and 8x on the PI graph. I’m liking it.
