MediaStudio vs. VS X3

[EdSE]

I am not sure if this is a valid comparison, but here it goes.... I was and still am a MS7 user and love it. I wish I could run it in my new HP laptop but I have W7 Premium and as some of you know, there are hard/software constraints that prevent me from doing so. Consequently, I went for VS x3 because I find that there are quite a bunch of similarities between the 2, although I wish there were more of the MS7 capabilities in VS x3. Anyway, my question is to those who have used both:

Have you noticed a difference in video quality (AVI-SD)? I happen to view an old video edited in MS7, compared it with my recent project in VS x3 and the MS7 video appeared to be of slightly better quality. Has anyone noticed this or is it just me? Thanks!
