I've tried a couple of setups using nLite, it's truly amazing what this program can do. Now, I don't like Windows Media Player 9/10/11, so I removed it in the nLite wizard. I also removed the possibility to install later versions of Windows Media Player - the option which appears very late in the wizard, I think it's right before you make the ISO. Though, I kept the 6.4 version (marked red by nLite), because I've heard that you need it for playing Windows Media files. Installing my "diet XP" (ISO files was only 249 MB!), and using Media Player Classic, I've found out that WMV files cannot be rendered. Does anyone know what this problem is related to? As I wrote, I did keep the 6.4 stuff (Windows Media core related, right?), but not compatibility for installing WMP later. Is this the reason? I suppose the reason cannot be that I removed WMP 9? Grateful for any advice, LA EDIT: By the way, I'm quite sure that I also removed something like "Media Center".
