I have bought my tm700 last year, and I didn't come across that problem. HD Writer worked fine for importing videos when i connected camcorder to PC. I was wondered whether you have turned on your camcorder when it was connected. If it was not a problem, you can try this camcorder assistant software-Final Mate i searched from goole, which also provides smart camcorder wizard for quickly and easily importing files from TM700. Hope it helps.

I have a new panasonic hdc-tm700. Tested it out before my vacation and was able to record video and import video through hd writer. Post-vacation, I have 5 hours of video on it and have just spent all afternoon trying to import with no success.
Problems are:
1. HD writer smart wizard won't start when I connect camcorder to PC
2. When camcorder is connected to PC I can't open HD writer by clicking on the icon or going into programs
3. Can't safely disconnect camcorder either by clicking on the little button on bottom right
I'm so frustrated I could cry. I've get a gaming computer so it should be fine, and was fine before when I connected the camcorder.
Any help would be greatly appreciated. My computer keeps locking up and I have to keep restarting it every time I try to do anything with the camcorder.
