I'm happy to announce that today, the MSN Remote Record Service for Windows XP Media Center Edition has officially launched. Now you can set your Media Center to record with a Passport account and your browser - just select a program in the Program Guide (EPG) on MSN TV Entertainment and click to record. Setup will handle the rest with you  step by step. Never forget to record that special when on the road or in the office. Note: Only one Media Center per Passport account at this time.
