Is the drive in your computer a DVD drive or a CD drive?
If it is a CD drive, it won't be able to read DVDs.
If it is a DVD drive, do you have the make and model of the DVD drive you are trying to play it on, but can't? Most DVD drives, now, can handle DVD+ and DVD-, but some of the older ones only handle one or the other so it is possible that the drive you're trying to read the DVD from cannot read that Disc type.
Its possible that the DVR is encoding it in DivX and that you don't have the codec on your computer.
First, I'd pop the disc into the DVD drive on your computer and see if you can browse the disc to see any file/folder structure. If so, its possibly a codec issue and I'd try downloading the DivX codec from www.divx.com. If it doesn't see the file/folder structure, the DVD drive can't read the disc...it is probably a compatibility issue as even some newer drives don't support both the + and - standards.
Let me know what you find.
I will download divx, the disk does not open to see the file structure, will install divx and try again
With technology constantly advancing, new formats come out and devices don't always recognize those new formats. It appears that the DVD drive on your comptuer doesn't recognize the formatting of the DVD that you created. In this case you have a DVD+RW and I'd venture a guess that your DVD drive only recognizes DVD-RWs....This would be why it can't even read the file structure of the disc.
It is possible that the manufacturer of the DVD drive has published a firmware update for the DVD drive that might allow it to recognize the DVD+RW format. I'd suggest you go to the manufacturer's website and see if they have one that you can download and install. If that doesn't work and you need to be able to read the DVD+RW disc, the easiest option might be to go to your local store and buy a new DVD drive that supports both the + and - formats.
