Hello to all, I am new to the forum. I have a huge issue that I would like to request some ideas and opinions on. If anyone has any ideas or suggestions of any kind please respond. I am currently in the middle of a DVD data distribution. I have several machines running windows XP and Sonic Digital media plus 7 to burn dvds. (Consider this as office location 1.) This is where the masters are being burned from Hard drives. There is a secondary location which is office 2 and this is where the dvds are being tested prior to being distributed. DVDs that are burned in location 1 read fine on various different types of PC's in that location 1. When these DVD are tested on various PC's in location 2 they take an extreme amount of time to install or copy to the hard drives. An example would be: A DVD burned in location 1 takes about an hour to install in several different machines in location 1. Same DVD will take up to 5 hours to install on various types of PCs in location 2. All are fairly new machines by the way. In location 2 I can install the DVD burned from location 1 and then burn a new DVD from the Hard Drive and it will go copy back in location one in 30 minutes. I had location 1 try burning with Nero 6 and in some machines it did speed up the install but in some in location one it wont even recognize the DVD. I realize this is a mess and there is something that is not right here. Any ideas, suggestions etc would be appreciated. In my honest opinion I think there are to many variables here but I have never seen this issue with DVDs before. Again anything would be appreciated.
