If you go back to cat 5.2, and mmc 9.03, you also have to go back to 2.5 for the remote wonder. Also, make sure you install windows media encoder 9 and the DAO MDAC update (filename mmc-9-1-0-0-dao-mdac.exe) first, before you install the catalyst drivers and MMC software. As before, you should uninstall everything (ATI drivers, remote wonder, MMC), reboot into safe mode, clean everything with Driver Cleaner then go back into Windows, install DAO MDAC, ATI Drivers/control panel, reboot, install MMC, reboot, install remote wonder software, reboot. Also, make sure your USB reciever for the remote is getting power from the USB interface (red light should be on). Good luck.
