Asked ATI about the Multimedia Center Support here is the reply:
"There will not be a Multimedia Center for the Theatre 550 based TV cards. The Cyberlink program is meant to be a replacement for the Multimedia software."

MMC 9.03 並不支援 550 Pro, 本來說 9.04 會支援, 但是 9.04 被取消了.
將出的是 9.06, 並不支援 550.

一個不支援自己硬體的公司, 怎麼能讓我買他們的東西?
