Sorry if this has been discussed to death already, I just came across it and would like to save someone else the hassle that I had.
The quality of the 1394 output video depends on the size of the preview window inside Vegas (I'm using 4.0, stretched across 2 monitors). If you have a small preview window at the bottom of the PC monitor screen, the external TV picture will be terrible, even if you use Best quality preview. On the other hand, if you detach the preview window and resize it until the video is full size(720 x 576 for PAL, 720 x 480 for NTSC) then the external picture is fine.
