Replying to HV30 video transfer problems

Alright so i recently got a new HV30 shot some test footage connected my cam to my computer and went to capture it to my computer. this is when problems started the in sony vegas i selected HDV for capture mode and it accepted it when i tried to record it would only display a black preview and just sound, thinking nothing of it i continued then when i tried to play it it wouldnt let me only displaying an notification that is couldn't play it asking me if i wanted it to keep the footage but keep it offline it records in DV just fine and shows up as .avi and I have a preview. the cam is set to regular HDV mode

is there a software that would just convert it off the tape into a video format like mpeg, mp4, avi, ect.... then i would just have to drag those files into vegas?
