Welcome to the forum.
Any plans for this anytime soon?
Unfortunately, this is a User-to-User forum. There is no Adobe presence, beyond that red A logo at the upper-left of the forum page.
Also, because I'm using the trial--what's the deal with the watermark?
That is the limitation of the trial. In PrPro, all things MPEG are disabled. There is nothing (that I know of) disabled in PrE trail, but it does watermark the output. Here is the FAQ Article on removing the watermark, once one acquires the full version.
As far as your camera, you will need to copy your material to the computer's HDD and Import that, rather than Capture, which would be used for miniDV tape cameras.
I have no idea why your Get Media/AVCHD downloader isn't working. It absolutely should, if your hardware is properly hooked up, your system is tuned and up to date and your Premiere Elements project is using the proper project settings. So there's really nothing to "fix".
I have the same problem with my Canon HF200. Fortunately, this one only has external flash cards, so I just put the card directly into my card reader and imported the movie from that.
I've still not been able to figure out why it cannot import directly from the camera.
With some flash memory camera/cards one does have direct Import. With others, one must Copy the files and Import from the HDD.
I am not sure about your particular camera, but others will likely know it, and can give you complete instructions on how best to get the files to the computer.
I have this HF200 unit and importing stuff is really the least of the problems. As indicated elsewhere the whole 1080i AVCHD support is essentially broken. Unless you're able to put up with extrodinarily bad deinterlacing or Canon's blur-o-matic 25p setting.
Can only assume that it's all work in progress. I was a hair from laying down cash before giving the demo a spin, pretty lucky escape. Oh well, PE9 perhaps?
I have the same problem in 8.0 so you're not alone.
