Hi-def camcorder video playback from file

[diamondcobra]

If anyone uses a hi-def camcorder, can you tell me how you store your videos for hi-def playback?  I have the Canon HV10 which does not play off the camera in hi-def - you have to import everything to your computer and then create your video file.  I dont have any sort of hi-def burner, so I want to play the videos at their highest res (it records at 1080i) over hdmi.  Using Sony Vegas, I get a zillion options for output format, so before experimenting with each, I thought I would throw this question out to the group.  Does anyone have a preferred file format for hi-def?
