I have followed the install instructions, and still having issues with Media Center for XP. Please see attached zip files as instructed.

1) You did not follow the instructions
2) You are including more hotfixes than those that are known to be supported
3) You are using a very old version of HFSLIP which isn't optimized for XP Media Center Edition
4) You have edited the HFSLIP log file

I can't help you before these are rectified.
