I have similar problem...
I have TV WONDER PCI, running Windows XP SP2

After I installed DAO, WMP encoder 9, and driver, I tried to install ATI MMC 9.2
The install shell runs for a while and extract, but no farther installing screen showed.

Basically what I am saying is, somehow I can't install ATI MMC 9.2. There is no error message or anything, the installing process just quit everytime I run it. I tried MMC 8.8, 9.0, 9.1, and they all did the same.

Anyone have any idea what is going on?
