HDV not available, missing codecs?

Hello,

Since some weeks I can't select HDV in the main menu of Premiere Pro CC, only DV is available. Is this a bug in Premiere Pro CC, or am I missing codecs?

Windows reconizes the Canon XH-A1, but I can't capture HDV, all my settings on the Canon XH-A1 are correct, but it doesn't work. Maybe a firewire problem driver or mpeg codec problem?

Thanks!
