I purchased the QT 6 MPEG-2 Playback component awhile back. I redownloaded it from the Apple Store (for free) to obtain the version that works with QT 6.4 or later when that became available in October 2003. VersionTracker claims that a version 6.5 was released on 5/11/04 and that a version 7.0 has now been released. However, if I pull down my previous purchase again, I'm still getting a package identical to the one I pulled down in October 2003. Do you need to repurchase to get version 7.0? The way I read MPEG-2 Playback FAQ, I think I'm probably getting the latest available when I redownload. But VT's claims that two versions exist that are later than the one I have make me wonder.
