I recently got a HF100 (I thought I'd skip the 16GB internal memory of the HF10 since it raises the price $150 but a 16GB class 4 card is only $32 online). The HF11 is the newer version of the HF10. It is a better camcorder (with 32GB built in) but it's also $350 more than an HF100. I looked at that one really hard but even after you buy two 16GB cards for an HF10 there's still almost a $300 difference and price and the improvements in the HF11 didn't look like $300 worth of better to me. Just my opinon there.
SVRT is just a technology to only re-encode elements of the video where it's needed. Click on the main button and select: view/SVRT information. That places a color code on the timeline to indiciate what SRVT is going to do with the video. Look up the SVRT help file built into Power Director. It explains the SVRT color coding.
The ImageMixer software that comes with the camcorder is pure crap. When I opened my HF100 box that disk saw the light of day for 2 seconds as it went for a short trip to the trash can. Try changing the file extension to mts. As far as I know, mt2s and mts are the same thing and some players will only work if the extension is mts. Also install an h264 codec.
VLC will play pretty much anything (and it's free):

Try reading through the Canon HF10/100 owners thread here for information on dealing with the MTS files:

I honestly haven't had much time to play with my HF-100. I've been too busy working with Christmas DVD projects using older video and pictures to have any time for it at all yet excepting starting to capture some videos.
Remember for watching the MTS files on a PC you have to de-interlace the original MTS files from the camcoder. Really for PC viewing it's better to just convert them to 720p. And of course to really watch the videos your camcorder makes in HD you either need a BluRay player or you have to directly connect the camcorder to an LCD via HDMI. There's no other way (well there is but it requires a PS3 and if you have that you have a Blu-Ray player as well).
Good luck. Nice Camcorder
