Did your verify the burn when you created the disc? I would say that you have a media issue or a burning issue if the game freezes. Try burning another disc, here is some rules I made up for myself when I burn DVDs.
1. burn at 4x
2. verify the burn
3. no multi tasking (don't run other programs, no downloading, and no web surfing)
4. make sure the virus scanner or screen saver don't start running.
When I start the burn I just leave the computer alone until the burn is complete.
If none of this works I would say try a different type of DVD -R.
