Hi all,
Has anybody else found that their HD-100s have the same 64-bit Firewire "globally unique ID"? Our project has received two, and they both appear to have the same GUID: 0x0080884f4f000000. When we plug both into a Macintosh at the same time, it refuses to talk to either. (We are able to use both cameras at the same time with Linux, which seems to be more tolerant.) I guess it is rare for anybody to want to use multiple HDV cameras at the same time on the same Firewire bus, but it's disappointing that JVC would violate the Firewire specification, if indeed that is what happened.
In other news, we've found that some of the DV long-distance cables (like Datavideo's, at http://www.datavideo.us/products/cables_main_page.htm) do not work with the HD-100 in HDV mode, because even though HDV only 19.4 megabits/sec, the Firewire chip the HD-100 uses in HDV mode tries to use Firewire's 400 Mbps "S400" mode, which those long cables aren't rated for. We'll test one of the Firewire-over-UTP extenders next week to see if that works.
