From: Michel S. on 8 Mar 2006 16:29 Hi ! I just bought a Memorex DVD-R spindle. Both the package and the disk shows "16x" as the maximum write speed. I made a test burn and Nero refused to write at a speed higher than 8x. Nero DVD-Speed (Disk Info) shows the following "basic" information : Disk Type : DVD-R Book Type : DVD-R Manufacturer : Ritek MID : RITEKF1 Write speeds : 4x-8x <---- ?? where's the 16x ? Blank capacity : 4.38 Gb My burner is a LG GSA-4163B, firmware : A106 (the latest) Am I missing someting or did I bought a "mis-labeled" batch ? Thanks !

Check the reports on videohelp etc with that particular MID. http://www.videohelp.com/dvdmedia.php?selectmedia=3395#comments http://www.videohelp.com/dvdmedia.php?dvdmediasearch=&dvdmediadvdridsearch=RITEKF1&type=1&size=All&dvdburnspeed=All&order=Name&hits=25&search=Search+or+List+Media http://www.google.com.au/search?hl=en&q=RITEKF1&btnG=Google+Search&meta=

Surprising.. According to LG site, this drive is a "16X Super multi DVD Writer". And the firmware version history shows that RITEKM16 DVD-R are supported since A105. A101 - Improves DVD recording quality. A102 - Addition of DVD?R 8X codes. ==> DVD+R 8X: Beall, Daxon, Intermedia, Infodisc, MBI, MJC, NANYA, OPTODISC, SKC ==> DVD-R 8X: Vangurad, RITEK, OPTODISC, MUST, AMC, Infodisc, DAXON - Improvement of DVD?RW rewriting ability. - Improvement of DVD+R DL writing quality. A103 - Fix writing fail on some DVD-R 8X, 16X & DVD-RAM A104 - Improvement of recording quality and readability of DVD media. A105 - Addition of new DVD codes - DVD-R: Optodisc(OPTODISCR016), Prodisc(ProdiscF02), Ritek(RITEKM16) - DVD+R: UME Disc(AML 002 0), DAXON(DAXON AZ3 0) (Enhancements of A106 are not listed on LG site) >> Blank capacity : 4.38 Gb > >> My burner is a LG GSA-4163B, firmware : A106 (the latest) > >> Am I missing someting > > Yep. > >> or did I bought a "mis-labeled" batch ? > > Check the reports on videohelp etc with that particular MID. > http://www.videohelp.com/dvdmedia.php?selectmedia=3395#comments > http://www.videohelp.com/dvdmedia.php?dvdmediasearch=&dvdmediadvdridsearch=RITEKF1&type=1&size=All&dvdburnspeed=All&order=Name&hits=25&search=Search+or+List+Media > http://www.google.com.au/search?hl=en&q=RITEKF1&btnG=Google+Search&meta=

I am not sure where nero gets their info. The do maintain a cdrom.cfg resource file for audio extraction rates and look up values in that file. A grep thru their code does not show tables of drive names so I assume that nero.exe and infotool.exe query the device. Their infotool is known to not always to report correct capabilities, both drive and controller. I upgraded the dvd firmware in two slightly different and older thinkpads. Both before and after nero infotool incorrectly listed both dvds (one dvd-rom the other dvd-cdrw) as *NOT* capabile of DVD+R reading. That was incorrect. Not only were they capable of reading DVD+R they would also handle DVD+R DL just fine and I was able to verify that. I really dont know where nero gets their info, assume there must be some codes in the firmware of the device they lookup. My guess is that the device capability might be influenced by sales staff more then engineering. They would get into legal trouble if they said it read +R/DL and it didnt. If it only worked at 4x and not 16x they could always blame it on the media and you really cant find fault with that approach. I tried burning a +R/DL on both a benq 1655 and a 1620 both with latest firmware. Nero 7.0.8.2 allowed 2x and 2.6x on the 1655 but only 2.6x showed up on the 1620. I would think that if it could do 2.6x it should allow 2x for a safety margin. I have also seen this on CD-R not just DVD. On one burn I did recently, I noticed that nero's speed could not be set lower than 32 (as I recall), but I was using a really old cd that I wanted to get rid of and I knew when I bought it years ago the media was not capable of more then 4x. Nero must depend on the device to report back speeds. I inadvertantly burned a dvd+r at 8x using nero. I forgot that both the source and destination were on firewire. After clicking on start it dawned on me that it was not going to run faster than about 2x if that much. I never saw the HW buffer get above %80, not even once. It consistenly stayed at %20 and hit zero a bunch of times. It started off saying 15 minutes and ended up done 2+ hours later. Verify worked fine! However benq implemented buffer underrun on their 1655 they did an incredible job ( i do now work for benq). I thought for sure I had a coaster. I have a pioneer A08 that I know would have failed in the same situation. -- ======================================================================= Beemer Biker joestateson(a)grandecom.net http://TipsForTheComputingImpaired.com http://ResearchRiders.org Ask about my 99'R1100RT ======================================================================= |
