Okay, so I'm finding out that the last few dvds in my batch of staples DVD-R are not working correctly, the past two games I've burned: Mushroom Men AND Guitar Hero World Tour stop reading the disc, Mushroom Men before it even GETS to the game and World Tour as it's loading the progress bar with the guitar hero logo menu. So my question is what is the best DVDs to use for this process?? I'll go out and get them this evening if somebody could please reply....also, is DVD+R or DVD-R better....and everybody is saying that burning speed does not matter is this 100% confirmed? I've burned at 4x since my first disc. Thanks for your quick replies!!
