Unless AMD/ATI changed things (or unless you know of some type of hack), the MMC install *REQUIRES* the original ATI Software CD. If I remember correctly, this is how they determine you've actually purchased the hardware (a requirement for downloading the software). If at all possible, contact the seller/giver and try to get that CD.
Note: The MMC install package has nothing to do with the Driver install, other than the drivers need to be installed prior to the MMC install. (
See here for components included).

Edit: The "TV player failed to initialize" error message your getting is likely because the decoder did not install properly (since you don't have the CD).
The lagging graphics could possibly be due to the limitations of the system you have it installed in or your power supply. I purchased a similar graphics card (AIW X800XL) for my older Athlon XP system and could never get it to run. I eventually RMA'ed it for a 7800GS. That card gave me crashing issues until I replaced the power supply (went from 400watts to 500watts. Don't remember what the amperage difference was). Even though the crashing stopped, the system still lagged in games. Moved that card into a newer s939 system and it worked as expected (no more lag).
