I've always used this Canopus ADVC-100 to preview Vegas on a CRT monitor, and lately its bothering me that there's a slight video lag. Feels like maybe half a second, but when you run into a project that involved syncing audio cues its less than ideal. I've just always assumed that its normal for the firewire to lag a little since it has to pass through the converter box, but I'm wondering if between everyone else's experience there might be a better solution?
Do you all use faster devices that can pass a signal with no delay, or is everyone in the same boat as me and just not bothered by it? At home I can use my hdtv's dvi input to have vegas just preview on a second monitor, but the office I work at is a little behind the times when it comes to hdtv.

Did you recently update to a newer version of Vegas?
The reason I'm asking is that, after upgrading to Vegas 7, I noticed a susbstantial video lag on my external monitor.
I don't use a Canopus box like you do.
My computer is hooked up to a JVC dual miniDV/SVHS deck.
The analog out of this machine feeds my 15" JVC monitor.
My solution was to adjust the sync offset.
Go "Option - Prefs - Preview Device" and adjust the "Sync Offset (frames)" slider.
On Vegas 6 on my machine, it was set to 4 frames.
With Vegas 7, I had to set it to 12 frames (the max) to get things back to normal.
See if this solution works for you.

Glad to hear that it worked for you!!
I got used to watching it on the Preview monitor until I stumbled across mention of this method on a Vegas forum somewhere. Sure glad I did :-)

Charlie, like you, I have yet to do any HD.
Our current setup (yours & mine) isn't capable of displaying HD because most of the components are only SD-capable.
As I recall (and someone please correct me if I'm wrong), the way most folks are getting an HD signal to a monitor is by using the "Windows Secondary Display" feature that's a part of Vegas.
You'll need a graphics card capable of handling the necessary resolution.
