I've confirmed the AV700's host port is powered, as it works with my flashdrive - I just wonder if it has enough juice to host an actual bus-powerd USB HDD, which will consume a lot more power than a flash-based drive.

OK, more testing...
The hub does not have enough power to power a bus-powered USB HDD. Here are the resutls of my testing:
1. 256MB Flash Drive: WORKS
2. 1GB Flash Drive: WORKS
3. 30GB USB Drive NTFS w/own power: DOES NOT WORK (error message)
4. Same as #3, reformatted to FAT32: WORKS
5. 100GB USB Drive NTFS, bus-powered: DOES NOT WORK (get's hung on "USB Device" screen)
6. Same as #5, w/own power: DOES NOT WORK (errors message)
So, that pretty much confirms that the AV700 cannot read an external device formated to NTFS, which also means the largest external device it can read is 32GB, becuase that is the size limit imposed by the FAT32 files system. I also confirmed that the AV700's USB host port cannot power a 2.5" bus-powered HDD. I wonder if it would work on one of those little 1.8" drives which are supposed to sip power.
The 32GB limitation is the biggest one of them all. I wouldn't mind carrying around an external HDD if I could get one between 100-200GB to work - which would easily accomindate nearly every DVD I own (in avi format) plus my entire music collection.
I already have the 30GB USB HDD, which I rarely use, so I may go ahead and load it up with stuff, especially since I've discovered that the AV700 can play directly from the USB device, negating the need to shuffle files between the AV700 and my USB drive.
I hope this info is helpful for someone else out there with the same questions.
