If you can burn a CD or play a DVD, then there's no problem with your computer. At least that's not the problem.
First, try a different DVD+-R. Memorex may not be able to handle all blanks equally; try using another brand. I've found that works for me. (Once I tried a package of single-layer Memorex DVDs - and none of them burned.)
Next, master at the slowest speed possible - 2x or 4x will give more reliability than insisting on the 8x speed.
Finally, rest things out with a single-layer DVD-r so you don't lose all your money on expensive DL blanks.
Oh, and leave your results here, so others can profit from your results!
ive tried the 2x and 4x write speeds. gives me the same result.
and as for trying another brand of blank media. I honestly dont see how that should change anything. I got 2 Memorex 100ct CD-R's last year for $10 each. out of the 125 or so of them ive used the only problem discs have been things that are my fault i.e forgot to plug it in and battery died etc. The media is designed to be written with the standard dvd format (ISO – UDF version 1.02 format ) or what ever format idvd writes in.
the blank media brand shouldnt matter when its being loaded with the format its designed for
Ah, that's different with those results. You might try going to Disk Utility and do a permissions check. This often corrects problems with DVD authoring.
If not, however, you might visit your local Apple Store/Genius Bar. When you duplicate the results for them, there's a good chance that they'll be able to root out a solution.
Permissions check should be the problem because i do that every few weeks and all that ever comes up is related to java. But i will try it again.
And i thought of something else that makes this problem really weird. I've been able to burn a dmg Install disck of Ubuntu to dvd.
So the problem is now i CANT burn a Movie to dvd
