I never used it but I thought the video input was on the front of the unit for the upload.
Various USB_.dll files were updated, I do not know if that opened the function of the usb ports or not. I would guess not.
The Audio/Video Inputs are on both the front (covered on the Sony) AND back (next to the outputs) of the UTV.
When you say that "various USB_.dll files" were updated... are you referring to UTV OS 3.8 or something along those lines?
Not sure anything will change with "updated" drivers but if someone happens to see their UTV's USB functionality change I'm sure we'd all love to hear about it.
