I had a problem when trying to render anything HD - usually after 2-3 minutes into the project. I fiddled around with all kinds of settings in Vegas and with the operating system. Here is my solution so far though I still need to test on several more projects to see what has actually done the trick.
First, the problem is some kind of memory leak issue from what I can tell and if you watch Vegas' memory usage, you'll see it ramps up and locks up the program or your system entirely with over a GB of memory usage or close to it. (When I made the page file adjustments below, the usage dropped in half and stayed stable throughout.)
So, what I found that corrected the problem was this:
1. Set your threads to 1 in the Vegas preferences (Dual Core system). Can't tell you what a quad-core would need yet.
2. In your system settings, make sure Windows is managing your Page File on your hard drives (in my case, drive C and D). I had it set on a custom size and that, I believe, was the problem.
I messed with all kinds of settings (RAM preview settings - why should that make a difference? but it seemed to make the lock ups happen later in a project). Only the two things above have corrected the problem so far. I still have some more render tests to do to see if indeed the threads have to be that low.
Let me know if it works for you
