The DH4B1S burner is having communication problems: look for updated drivers for the motherboard's chipset or SATA controller where the drive is connected to. You might also want to try another SATA cable too. If it still gives this error try what this post from the FAQ says.
As for the HP burner it doesn't seem to properly support that media (e.g. 2.4x isn't a valid speed for the DVD-R standard). Try this firmware update to see if it helps. You could also try burning at 4x or 8x and maybe running a lens cleaning disc on that drive.
Media that doesn't work on three quite different burners tells us a lot about its quality, doesn't it?
Ok everybody thanks for all your help. But i was able to get it burning again. Just want to let everybody know how this all started. I was using vista to burn my wii iso was able to burn on 3 different dvd burners 150 different iso on many different kinds of media from no name media to high end. I purchased a blu-ray burner and visted would not see it so i went back to xp and that where all my troubled started. could not burn on three different burners. so i put my old no name burner in and i was able to burn on that drive again (see log below). So that got me thinking the problem must be between xp sp3 and imgburn. So i stuck my blu-ray, my liteon and my hp burner in a xp machine that only has xp sp2 on it and all three burners worked again. So i then put them in a vista sp2 machine and and 2 of the 3 worked the blu-ray burner would not. So i hope this little test on mine helps someone out there because i know i was very frustated that everything stopped working.
