Recently, I've found that this bug may have resurfaced.
When I hook up two ADVC-55's to the same machine (even on different
Firewire bus), then the OS seems to not recognize either. That is,
where one would select a video device, neither is available.
The two ADVC-55's were purchased at the same time, and are new
(well, .. as new as last month). (Multiple devices work, as long as
there are not 2 identically named devices).
So I believe it is a problem "again", although I know that it was
previously "fixed".

Hi Glen,
FYI, we just tried a ADVC 110 and an ADVC 55 on the same machine
(mbp 17 Core duo, 10.5.2 ) and it work under QC, though it took a
few tries to get it working.
Tried it in another program (NuVJ) and it didn't work, but this may
be a limitation of that software...

There was previously a QuickTime restriction of multiple DV
devices on a firewire bus. This was resolved in Leopard.
I currently have 2 ADVC-100's and one Sony DMC-DA1 running
simultaneously, although the application is SecuritySpy, and not a
QC composition.
However I can vouch for the fact that the QuickTime restriction
has been addressed.

This thread
http://lists.apple.com/archives/streaming-server-users/2006/Jul/msg00096.html
suggests that this may be a quicktime driver problem since the
digitizers both ID with the same name? However, that was back in
2006, so I'm hoping things are different now.
Of note, System Profiler shows both devices with same name, but
different GUIDs.
Anyone know if it's possible to get two (or more) of these
devices working at once in QC?
If QC can't handle it, would it be possible to cook up a simple
custom patch which does nothing but pull video input from a
device specified by GUID?
