Posted above in media discussion group by mistake. I believe it belongs here...

I've just created a series of 2 minute videos and copied them onto a DVD-R disc using a frestanding Toshiba DKR2SU DVD recorder. Since I'm making 40 copies, I've tested it's playability on 4 computers and 3 freestanding DVD players. It works and plays fine.

Today, I began the process of making copies. Boy, did I get a surprise! I cannot copy the disc using ULEAD Movie Factory 3, or using the most current version of NERO. Ulead simply crashes as it starts to engage to copy the original to image. NERO, as I engage the copy process, coughs up an error message reading: UNEXPECTED EXCEPTION which does not have an explanation in it's help section. I might add that it requires a 3 finger salute to get out of Nero after the error message occurs. I've made exaustive variations of the process and nothing changes. It's still the same problem.

I'm lost and without knowing how this is happening, I don't want to take another 15 hours to edit my videos into a fresh copy, just to be met with the same disaster again.

Any ideas?

DVD-VR and DVD+VR these are the 2 standards for home dvd-recorders - the dvd-vr will play on most dvd-rw drives(computers) the other dvd+vr should play on home and computer players.....if you got the dvd-vr type then it needs to be converted then burned, try using nero vision express and add the dvd files in and burn or tmpg dvd author, i use both and have no probs with playback on any dvd player home or computer.

easiest way to copy a backup or home movie 1:1 is to use a free program called dvddecrypter which is now defunct; however, if you do a search you might be able to find it.

1. go to the mode tab and select ISO read. This puts an image of the disc on your hard drive

T2. hen go to mode tab and select ISO write. This writes the image to your dvd-r.

That's it.

late update:

Well, the answer to this was pretty simple. First, you have to have a totally good burn to get a good copy! I just re-authored the DVD, making a new master and it reproduced just fine after that.

Although the original master played fine on all my players, apparently, during the copying process, the master is read differently than when being played and that difference was enough to corrupt the copy process. Didn't think that could happen but it would appear that it can.

Oh well...
