Premiere Pro CS4 (4.1), AVCHD and Vista 64 vs. XP

Have been struggeling with PPCS4 for quite a while getting it to edit and play back AVCHD files (MTS: 720P 50) from my Panasonic AG-HMC151E without making trouble. I run PPCS4 on a Q6700 with 8 GB DDR2 PC800 RAM, Nvidia 512 MB 8800GT and Windows Vista 64 Business SP2. I have eidtted a lot of videos in HD from Canons HF10 without the big issues, but when I started trying to eidt the MTS files from my 151E I got nothing but trouble. It would not play back proberly, stopped, crashed, uses 100% CPU etc. I tried changing the Nvidia from 8800 GT to a brand new 9800GT with no luck. I even (after one week of testing and trying everything and after many hours with no sleep) thought about upgrading the CPU to Q9650 on my 1½ year old PC. I have been waiting for the 4.1 upgrade since late april and expected it to do magic, but NO. It helped a bit - I could now play back but only in draft quality. High quality did mess everything up as before (stopped, did not play smoothly at all). I was all most giving up today....BUT then I tried to reboot into my old old XP Pro installation (at the very same PC as the Vista 64). After updating PPCS4 once more in XP I launched PPCS 4.1 and HEUREKA. I imported a 2 GB MTS file in 2 secs - and playback: SMOOTH even in HIGH QUALITY!!!! What is going on here????? I know PPCS4 is 32-bit, but Adobe have written more than once about the 64-bit support and I have read about Vista 64 bit doing a much better job when working with PPCS4.
So what is the problem here? Why can´t I edit and play back smoothly using MS state-of-the-art system in 64 bit that is able to use all of my expenssive 8 GB of RAM - but have no problems using the old allmost dead system XP Pro - only using 3 GB of ram?
Adobe? Is this because you have not been doing your work proberly in trying to make PPCS4 doing a great job in Vista 64 or is it MS that has been doing a bad job? Who is to blame if any? Or is it just me having these problems with PPCS4 on Vista and not on XP Pro? Anyone else have a clue? I would rather get smooth playback in Vista 64 - I have paid for it all and I want 64 bit and all my 8 GB ram back, please!!!!
(PS: I use all the latest drivers: Nvidia 185 driver, latest BIOS etc.)
