Well, yesterday I finished 25-disk spindle of Memorex DVD+R DL. Everything burned very well with two (2) coasters only.
With my Pioneer DVR-108 I had the following results:
Memorex DVD+R DL - RITEK S-04-42 - 23 good burns with 2 coasters
TDK DVD+R DL - RITEK-D01-01 - 2 coasters - returned disks to the store
Verbatim DVD+R DL - MKM-001-00 - 2 coasters - returned disks to the store
I agree, I would probably have better results with new DVD-burner. However, I also agree that each burner has its favourite disks.
I am thinking about buying [B][SIZE=3]SONY NEC OPTIARC AD7191A-OB 20X LS.[/B] It has LightScribe. Any idea?[/SIZE]
As already pointed out in the similar thread here in BLANK MEDIA forum, the DVR-108 is a old DL burner (the first DL burner by Pioneer) and is not supported anymore since years. The only DL media you should try with is Verbatim DL media and it should work nicely if your burner is still okay and your setup/hardware/software too.
Forget all that other listed DL media.
Even they would burn successfully, scan them for quality and you will see why they are not reliable!
