2) Type of Disks Needed

You can't burn XBOX 360 games on any regular CD or DVD discs. There are special discs that have double the storage, and a double layer. These discs are called Dual Layer discs also known as DL Discs. The average price of these discs are around $20-30, The brand i'd suggest is "Verbatim" or "Memorex" Dual Layer 8GB discs. When you buy the discs (doesn't matter what brand) make sure it says "DVD+R DL" on and not "DVD-R DL"!

These disk are examples of the Verbatim 8.5GB DVD+R DL disks.
