[qanda]This thread is about the Pioneer DVR-K16. Click here to see full specs[/qanda]Hello, I’m new here.
Since now, I’ve been using Verbatim DL discs, they have worked perfectly - not a single bad burn. However, with new Mitsubishi discs, things have changed.
Anyway, i got myself Mitsubishi Chemicals DVD+R DL 8.5GB discs. Everything looked good, they have Media ID same as the Verbs. I also read from these forums confirmations that these discs are very good. So i bought 50 discs of those. Unfortunately they do not seem to work for me.
I tried using growisofs program under linux and saw a peculiar thing - as soon as it reached second layer the speed went down from 2.4X to 0.6 and the drive started spinning up and down, seeking… Then i noticed that UBU (Unit Buffer Utilisation) was jumping up and down between 2% and 100%…
I thought that maybe this is a bug with “growisofs”, so i booted into windows and tried IMGBurn, i selected .dvd file and tried to burn - same thing happened again, as soon as it reached 51% the device buffer started to go up and down and speed fell to 0.6x.
My DVD burner is Pioneer DVR-K16 rpc1 1.44 fw (UDMA enabled). Running windows vista 32bit or Gentoo (2.6.30 custom built kernel).
DVD+R DL’s are from Mitsubishi Chemicals with media ID MKM-003 (here: http://club.cdfreaks.com/f76/mitsubishi-chemicals-dvd-r-dl-97058/ )
