Just got HF10, did some test shots, wanted to transfer to my laptop, that thing tells me plug in power adapter; is there really no file transfer on battery power, or this is just a "user problem",
thanks guys!

Yes,no file transfer on battery power,but you can copy from internal memory to sdhc card on battery power and use card reader than ,much faster.
Thats why I shoot straight to 16gb SDHC card and leave internal 16GB as a reserve.

Wow , how couldn't I get to this on my own, perfect,
but I have an excuse, I just got my HF10 and didn't get any SDHC yet, which one should I buy to be ok for XP (17 mb/s) mode. I believe class 6 is too slow, x133 is also only up to 13,5, then what specs should be on the card,
Many many thanks!

class 6 is fine, in fact I have seen class 4 kingston work.

I am using class 6 kingston and sandisc extreme both work flawlessly on highest settings

I have the same on my HG10 (hard drive based). I was pretty surprised that it needed to be plugged into the AC adapter. I'm even more surprised that they haven't fixed this on the flash-based camcorders. Still, the card reader approach is a good one.

I wonder if that's just a safety precaution to make sure the battery doesn't die in the middle of a read/write, resulting in the flash becoming corrupted. Many gadgets, like the Sony PSP, require the unit to be plugged in during a firmware upgrade as a precaution.
