Hi, I've been making backups for about a year now and have 70 games that worked fine, not a single coaster. Now my last 10 burns have all died, I'm using the same media, as always verbatim DVD+R DL. I burn with IMGBurn on my Pioneer DVR111D, I read from a kreon flashed drive, but even discs I download don't work.
The Pioneer is working fine for burning Wii games, and other things, and IMGBURN verifies the 360 games as being fine, but as soon as I put them in the 360 it says Disc Unreadable.
I also notice that when I put the burned discs in the computer they don't show up like usual with the movie playing that says something about being needed to play in a Xbox 360console.
make sure your Verbs are made in Singapore ... there is a huge problem with the Verbs made in India ...
same as u - last year i had abour 50 successful burns on my resume - all of a sudden 18 coasters out of a pack of 20 ... that pack was Made in India ... little to no problems with Singapore ...
