| 1251015 | 2011-12-28 17:42:00 | OK - I can screw up anything Linux, but this is bugging me too . Let me ask a couple of questions::: 1) If I create an ISO copy of a DVD - then why can't any of my DVD players play it in the correct sequence? B . Why can I only play my ISO copies on my computers? III - Is this a stupid question --- or wot? Every time I make an ISO - it never plays correctly, but I can play it back on a computer - ANY computer really . I have several MODERN DVD players (read: less than a year old) - so I doubt that they are the culprit . Is there something Linux hidden in making an ISO and THAT'S my real problem? Linux hates me . |

| 1251017 | 2011-12-28 17:54:00 | OK - but I thought that by creating an ISO - it was an exact duplicate of the original DVD or CD. If it IS a perfect copy, why doesn't it act that way? Is not ISO just an image of the original disc? Somehow it seems to shuffle files and positions so that the CD or DVD playback machines cannot interpret the sequences. Some DVDs play from the middle - some miss whole files - some just play the same segment over and over - some will only play two or three files and ignore the rest. All I want to do is make a duplicate - no editing - just a pure copy of whatever I want to have duplicated. |

| 1251018 | 2011-12-28 18:25:00 | Unfortunately creating an ISO of a DVD isn't quite that simple, you need to use specific software to do-so. I used to use DVDShrink under WINE to do it personally. |

| 1251021 | 2011-12-28 20:46:00 | OK - but I thought that by creating an ISO - it was an exact duplicate of the original DVD or CD. It is. Hopefully this will come out right, I know what I want to say, but finding the right words without getting all technical it may read wrong. When you create a ISO image of a CD/DVD it is an exact image. If you can imagine taking all the files on the DVD, then bundling all of them into one container and sealing it as an ISO , then that image can be replicated back to another DVD and you will have the exact same contents. When the ISO file is created its a little like a sealed file, all its contents are in one place. When you burn it back to another DVD , all the contents are unsealed and laid back out as per the original. To create a ISO file of a current DVD is simple - (this is for windows) - download and install isorecorder (alexfeinman.com). Then simply put the CD/DVD you want to make a ISO of in the drive, right click it, Create image from CD/DVD, select where you want to store it, then next and it will make a ISO file of that CD/DVD. 3467 Take this picture, its the contents of Windows7 DVD that you use to install the OS 3466 After making the image I now have a single file. BUT if you try to look at the contents of the file in a zipping program esp the windows 7 DVD it doesn't actually show all the files. 3468 To burn the ISO file back to a DVD in its original format, you need ISO burning software, then it unseals the contents correctly and lays it back onto the DVD as per the original. I use Active@ISO burner, but there are many other different ones about. |

| 1251022 | 2011-12-28 21:16:00 | To draw an analogy, your DVD ISO is very similar to a HDD Disc Image or a Partition Image. It contains all the info to faithfully reproduce your DVD / Partition / Whatever down to the very last bit on every sector, but is not stored in a manner that exactly matches your DVD / HDD / Partition (eg it may be compressed, or stored in a proprietary format). |

| 1251023 | 2011-12-28 21:44:00 | Just adding to my above post -- making a ISO from a Movie DVD is exactly the same. Where problems may arise is if you are trying to do it to a commercial DVD and its copy protected. If you have a Homemade DVD for example, the easiest way is to do a simple copy, no need to make ISO files. Most burning software has this option. |

Wai, we have just copied a couple of kids programs Finding Nemo and Babe from HDD to DVD drive and it has the option to make the DVD readable on any player. We presume we can go in and adjust this on the header on the DVD?. Mind you it would be a good way to see the Grand kids eh, lol. Lurking. |
