Hi David,
Thanks. Some good pointers in there. I never thought that using the same drive as your installations would have an impact. That said, I rarely do that and try to use all separate drives for projects that way if the boot drive crashes, I don't lose my important files. Instead, it just makes for a week long effort to rebuild. lol
I will have to check out the speed test and verify cache location.
My first thought however was that there was just some procedure, similar to RAM preview so I was blaming Premiere for sure. :) lol Now Vegas, which I really have loved for years did seem to have that lag as far back is like 2005 or so when I began using it.
