If it flatout won't play, as oppose to stuttering etc, then usually the issue could be:
- Burn speed. You're burning too fast.
- Your media. You are not using A-Grade manufactured media.
- You're burning the disc outside of dvdsp and doing it incorrectly.
But there are a bunch of other issues it could be!!
YES Brand does kinda matter but the manufacturer more so and yep +/- can matter but it all depends where you disc is going to play!!
