Welcome to the forums.
As it happens, we had a similar question just tonight, and it is at the moment listed right after yours. Please see
http://phpbb.ulead.com.tw/EN/viewtopic. ... 768#156768 for my comments on exactly how demanding AVCHD (which is what your Canon films in) actually is. While you have a Core 2 Duo processor, it is at the bottom end of them, and I suspect you really need both to have upgraded to VS11.5+ with both the 6 November 2007 update patch and 8 Nov Power Pack, for your computer to begin to deal with AVCHD properly. And even then, I suspect you would need to use SmartProxy.
1. Probably not. You don't say what your operating system is, but if it is Vista, then extra RAM certainly helps with Vista alone -- but there is a quirk that Vista does not seem to be able to deal with anything above 3 GB of RAM particularly well. I have a HP Core 2 Duo 2.2 GHz laptop with 2 GB RAM which seems to be OK with AVCHD, though still rather slow. My Core 2 Quad 6600 seems much better.
2. Could be. Quite often, companies like Canon tweak programs to work with their hardware. I am also aware that one of our high def gurus, etech, says the full version of MF6 with update patches/power pack (i.e. not an SE version) does a better job more easily with avchd than VS11,.
3. I have no idea since I had no idea of your workflow. But it could easily be normal with your computer...
4. No idea what you are talking about. The only DSVD I am aware of relates to voice modems...
