wadoline Posted October 31, 2007 Share Posted October 31, 2007 Hi I´m trying to copy a *.nrg into a blank dvd without success. The dvd unit doesn´t recognize the disc (it´s a navigation disc and the unit it is a specific DVD player (Mercedes Benz) that only recognize the original navigation dvd). I know that some people are working with a copy of the original dvd. Could you help me? I´ve burned 10 dvd at low speed (verbatim and sony) without success This is my configuration: SONY DVD RW DRU-700A VY08 (ATA) Current Profile: DVD-R Disc Information: Status: Empty Erasable: No Free Sectors: 2.297.888 Free Space: 4.706.074.624 bytes Free Time: 510:40:38 (MM:SS:FF) Supported Write Speeds: 4x; 6x; 8x Pre-recorded Information: Manufacturer ID: SONY16D1 Physical Format Information (Last Recorded): Book Type: DVD-R Part Version: 5 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 1 Track Path: Parallel Track Path (PTP) Linear Density: 0.267 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196.608 Last Physical Sector of Data Area: 0 Last Physical Sector in Layer 0: 0 Best regards Link to comment Share on other sites More sharing options...
blutach Posted October 31, 2007 Share Posted October 31, 2007 Most, if not all, car nav disks are written PTP and not OTP (like all dual layer media is). They can't be copied. Get a Tom Tom or a phone with a nav built in (for some reason I have both - it gets confusing when they don't agree which route to take!!!).

wadoline Posted November 1, 2007 Author Share Posted November 1, 2007 Hi again! But there is people that are working with a copy fo the original dvd and people that have problems with the copy (sometimes work the copy and sometimes not). I think that maybe is the setting of the copy. What do you think? Regards Link to comment Share on other sites More sharing options...
dontasciime Posted November 1, 2007 Share Posted November 1, 2007 But there is people that are working with a copy fo the original dvd and people that have problems with the copy (sometimes work the copy and sometimes not Ask them then If your not happy with the answer you got here Link to comment Share on other sites More sharing options...
lfcrule1972 Posted November 1, 2007 Share Posted November 1, 2007 I am with blu on this I thought all Nav discs were PTP therefore could not be copied and written to current blank media. As donta said if you know someone who has got round this I would speak to them Link to comment Share on other sites More sharing options...
wadoline Posted November 1, 2007 Author Share Posted November 1, 2007 I have speak with them and always said the same. They burn the discs with Nero or Alcohol without problems. There is other people that have problems sometimes (the have to insert the disc many times until it works) and there is another people like me that nothing of nothing. I have tested with two recorders and nothing. Maybe is the player that only works with the original disks Thanks for your help! Link to comment Share on other sites More sharing options...
Shamus_McFartfinger Posted November 1, 2007 Share Posted November 1, 2007 I agree with the guys. This has come up many times over the last couple of years. If the source is PTP and your burner uses OTP (which it does), then doing a standard copy just won't work. It's part of the copy protection which we won't discuss here.

wadoline Posted November 1, 2007 Author Share Posted November 1, 2007 Oh sorry guys!! I wasn´t understanding you... Then If I buy a OTP burner maybe the DVD works in the player? Can you recomend me an OTP burner? Thankyou !! Link to comment Share on other sites More sharing options...
Shamus_McFartfinger Posted November 1, 2007 Share Posted November 1, 2007 You seem a little confused. Let me help. OTP - Opposite Track Path - Disk reads from the centre to the outside edge then changes layers and reads from the outside toward the centre. This minimises the time it takes for the laser in your DVD player to re-focus on the second layer when you watch a movie, for example. (Called the "Layerbreak"). PTP - Parallel Track Path - Disk reads from the centre to the outside edge then changes layers and reads from the centre to the outside edge again. With the exception of developer drives , almost all burners are OTP. Burning PTP (like a GPS disk) as OTP places the information contained on the disk in the wrong place. As I said, it's part of the copy protection. Link to comment Share on other sites More sharing options...
wadoline Posted November 1, 2007 Author Share Posted November 1, 2007 Ok! But the image dont uses a DL disk, only needs an SL disk The image has only 2.952.769 KB Is it necesary the PTP in a single layer DVD? Link to comment Share on other sites More sharing options...
Shamus_McFartfinger Posted November 1, 2007 Share Posted November 1, 2007 If it's single layer, then it should read from the centre out. If a standard ISO Read/ISO write fails and your media/drive isn't the problem, then there is likely copy protection of some sort present. We cannot help you with anything that involves the bypassing of any such protection. Link to comment Share on other sites More sharing options...

doxola Posted November 1, 2007 Share Posted November 1, 2007 I was able to make a working backup of my Pioneer AVIC9 Nav DVD onto DL media. Maybe mine is from ancient times, but at least for that model, it worked. Link to comment Share on other sites More sharing options...
