Query: DVD-RW Drive

Product has excellent backwards compatability with current on the market DVD's (70-90%). Installation was not that hard. Would have given a 5 except that current support for Windows XP is not documented well. In general most of the documentation is lacking. 5 for hardware, 2 for documentation, 3.5 for software, which is included, but needs to be upgraded if you use XP.
