I have just done a fresh install of XP. When I tried to run DVD Windows Media Player report that no decoder could be found. I then installed the PowerDVD (4.0.08) from the CD that was shipped with the PC. When I ran "dvdupgrd /detect" it reports: DShow SW:name:"dvd.ax"Company Name :"CyberLink Corp."Version: 3.5.0.814Product version: 3.5.0.814CRC32: 0x9b4a1aedVID:2 When I run either Windows Media Player or Power DVD with a DVD in the drive, both pogramms report that they encounter problems and exit. So, I can't currently play a DVD. Q: Will the version I have still work, do I need any patches, do I need to install any additional Dell drivers? If this doesn't work, do I have any other options? All help appreciated. David   Dimension 4300 750Mb memory 160Gb hard disk XP, SP3, All high priority updates installed Windows Media Player 11
