Your Canon ES2000 is a Hi8 device that requires analogue capture. Use whatever has worked for you to date. What is wrong with sticking with XP and S9.43? Might you also be thinking about retiring the ES2000 along with the capture card?
Studio 14 presents some problems for people who do DV capture. No known comments from any Hi8 diehards loyalists. Any willing guinea pigs? Is your Last Will and Testament in order? Does your life insurance policy contain any exclusions for "videographic derangement" or "NLE toxins."
If you can find Studio 12 on-the-cheap somewhere, and install its 12.1 patch, it might add some new tools, entail little learning curve, not impoverish you, and entail less risk.
