Video Preview...not so good.

I'm just getting started with Vegas Video. I captured my video no problem. But, when I add a video overlay (in this case picture-in-picture), I have trouble previewing. It previews ok on the CRT (a little choppy, though), but when I use an external monitor (which is connected via firewire to a Datavideo DAC-2), I have big problems. The clip plays fine until I reach the overlay point. Then, the external monitor loses signal and the preview reverts to the CRT. Also, if I render the video to MPEG2 (for DVD), then bring it back in to Vegas, it won't play on an external monitor at all. Is this normal?

You need to select "recompress edited frames". **Options/prefs/external monitor
Now everything and anything will output thru your OHCI 1394 port.
You'll want to set preview quality to preview, not draft. "Prerendering" in "preview quality" will show more detail, full frame rate and renders very fast. Prerendering will also give you playback with fields so you can check for jitter on overlays,speed adjustments, filters, ect. Recompress looks to only be frames. Computer speed will effect when you start dropping frames.
I use a dual head Geforce MX 2 card for my analog tv preview. S-Video output to 13" S-Video NTSC monitor works great. Draft quality setting lets me get better frame rate than OHCI output. 640x480 window holds all of the action and title safe areas of the DV 720x480 signal.
I drop to 360x240 on heavy layer segments to see at full 30 Fps.
I use prerendering when checking things out the OHCI. Recompress is soft on overlays and doesn't show jitter.

Same recompress setting will play anything on the timline out as a DV stream.
