Preview Monitor out of sync

When I preview my project on my NTSC monitor the picture looks as though it is dropping frames and the audio does not match the video. Even when I apply transitions, they too look choppy. However, on the Video Preview in Vegas everything looks perfect. When I toggle from the Video Preview to the DV deck, the video preview sceen turns black and reads "Frame Recompressed" My preview monitor is connected to my DV deck via S-Video and the DV deck connected to the PC via firewire. The NTSC is great for checking colors, but deceiving when editing. Could this "dropping frames/audio sync" problem be a result of firewire connections. Please note that I am new to Vegas and any help is greatly apprectiated. One last question is there any easier way in vegas to sync a muliple camera video shoot? Basically I have a project where I used two cameras and did not use timecode as a referece point. Now I want to sync the two sources and pick and choose the scenes? Does Vegas do this? Thank you!

Thats not unusual and is discussed in the Vegas 4.0 manual--Essentially saying that its a function of raw power-----Having said that, if you need to see an accurate rendition to your NTSC monitor from the timeline--do a ram prerender-- then play back through the monitor.

Also, I find I get much better sync in preview if I use the "Windows Classic" audio drivers rather than ASIO.

If both cameras recorded the same sound, you can use the audio to synchronize the clips. It helps to enlarge the vertical size of the audio tracks and expand the timeline (zoom in) sufficiently to be able to match up the audio traces. This has worked well for me when I’ve used two DV camcorders and captured in Vegas. After the video clips are synchronized, I usually discard the audio from one source, keeping the better of the two, as this makes the cuts between cameras more seamless. The DV camcorders were not the same make/model so some color correcting was also necessary but easily accomplished by making one set of corrections at the track level.
