Using Sony camcorder software, ver 1, i believe, if you downloaded via firewire, the resolution was a much lower resolution than via analog. If you used another program, firewire transfered full camcorder resolution.
I know this was a know bug with sonys xfer software.
Do not know if resolved, since I have not used it since.
Firewire is the best, as long as you use something other than Sonys transfer program.
